Classify Rice Disease Using Self-Optimizing Models and Edge Computing with A...Damian R. Mingle, MBA
Rice continues to be a primary food for the world’s population. Over its complex history, dating as far back as 8,000 B.C., there have been agricultural challenges, such as a variety of diseases. A consequence of disease in rice plants may lead to no harvest of grain; therefore, detecting disease early and providing expert remedies in a low-cost solution is highly desirable. In this article, we study a pragmatic approach for rice growers to leverage artificial intelligence solutions that reduce cost, increase speed, improve ease of use, and increase model performance over other solutions, thereby directly impacting field operations. Our method significantly improves upon prior methods by combining automated feature extraction for image data, exploring thousands of traditional machine learning configurations, defining a search space for hyperparameters, deploying a model using edge computing field usability, and suggesting remedies for rice growers. These results prove the validity of
the proposed approach for rice disease detection and treatments.

Mass estimation of citrus limetta using distance based hand crafted features...IJECEIAES
Sorting and grading are qualitative operational tasks performed in food processing industries. Realization of higher accuracy in mass estimation is the key inclination of this work. In this work, an automated technique for mass estimation of citrus limetta is devised based on the geometrical features derived from pre-processed images. Dataset includes 250 data samples of citrus limetta, whose images are acquired in different orientations. Two novel handcrafted distance-based geometrical features along with four conventional geometrical features were employed for regression analysis. Predictive modeling is conducted with configuration of 150 training and 100 testing data samples and subject to regression analysis for mass estimation. Multiple linear and support vector regression models with linear, polynomial and radial basis function (RBF) kernels were employed for mass estimation with two different model configurations, conventional and conventional with handcrafted features, for which an R2 score of 0.9815, root mean squared error (RMSE) of 10.94 grams, relative averages of accuracy and error of 96.61% and 3.39% respectively is achieved for the proposed model and configuration which was validated using k-fold cross-validation. Through comparison with performance of model with conventional and conventional with handcrafted features configurations, it was established that inclusion of handcrafted features was able to increase the performance of the models.
This presentation represents the new way of analyzing food quality using modern technology of image processing.
Problem statement:
Many problems of food quality and safety have occurred in recent years. The quality analysis of the food items has thus become increasingly important. The system tries to provide the customer with highly improved and good quality of food using the modern technology of image processing and also the GPS technology for tracking food transportation. This would provide an improved way for quality analysis reducing manual efforts and error.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes.

Abstract
Agricultural and food products are present in incredible varieties in terms of shape, size, color and as the market
grows more demanding, food products are subdivided in various categories and are destined to different
segments. The definition and characterization of different attributes are very important for the business and for
the consumer, making it necessary to establish norms of classification and standardization, thus making
commercial trading more efficient and allowing for higher awareness on the part of consumers. A computer
vision system (CVS) have proven very successful in the analysis of food on the basis of color, size, shape,
texture etc. Computer vision is the science that develops the theoretical and algorithmic basis by which useful
information about an object or scene can be automatically extracted and analyzed from an observed image,
image set or image sequence. An image can be defined as a spatial representation of an object or scene. Image
processing is base of computer vision system. Image acquisition, processing, segmentation are basic steps for
extracting information of image. CVS system is being used in food industry for the detection of defects in
apples, oranges, olives, cherries etc., sorting of potatoes, online monitoring of baking conditions, measurement
of browning in chips. It is also being used for checking ripening stages of banana, tomato, cherries etc. Also it
can be used to classify different varieties of cereal grains and check their adulteration. It can also be used for
checking color of meat and lean yield. Computer vision is an emerging subject in food sector. It is a fast, noninvasive cheap method for evaluating quality of foods. The use of computers allows for increased efficiency
with less manpower, reduces dependence on trained experts which is costly and time consuming. Also, we can
do modelling of information obtained from image and can be used for future. This paper presents a review of the
main publications in the last ten years with respect to new technologies and to the wide application ofsystems

Introduction
The great concern with quality control due to
new market restrictions in recent years has become so
important that it has demanded a technology of
process geared toward more reliable tests and new
methods of monitoring product quality. Over the past
decade, significant advances in techniques of tests
have been observed, while extraordinary resources in
electronics and informatics were identified as
important factors in this development. Automation
has motivated the development of testing equipments
in production lines, and the evolution of sensor
technology has led to the establishment of new
techniques of measurement of the products, thus
allowing permanent monitoring during the process,
with the implementation of visual inspection systems.
In the food industry, some quality evaluation
is still performed manually by trained inspectors,
which is tedious, laborious, costly and inherently
unreliable
due
to
its
subjective
nature
(Francis.,1975).Increased demands for objectivity,
consistency and efficiency have necessitated the
introduction of computer-based image processing
techniques. Recently, computer vision employing
image processing techniques has been developed

rapidly, which can quantitatively characterize
complex size, shape, color and texture properties of
foods.
Systems of visual inspection are basically
composed of a light source, a device for capturing the
image and a computational system for the extraction
of characteristics and processing. These systems are
normally used in production lines where human
activity is repetitive, products are manufactured very
rapidly, and fast and accurate measurements are
necessary for decision making during the process.
Different from the problems present in visual
inspection performed by people, these kinds of
systems offer accuracy and repeatability in
measurements without contact, especially due to the
elimination of aspects such as subjectivity, tiredness,
slowness and costs associated with human inspection.
The use of automatized inspections in agriculture and
in food industry has increasingly become an
interesting solution for the final analysis of product
quality, and the assessed values or characteristics
involve not only dimensional aspects, but also
characteristics of color, texture and shape (Fernando,
A., Mendoza, V., 2005).
Agricultural and food products present an
incredible variety of shapes, sizes, colors and flavors,

and as the market grows more demanding, food
products are subdivided in various categories and are
destined to different segments. The definition and the
characterization of different attributes are very
important for the business and for the consumer,
making it necessary to establish norms of
classification and standardization, thus making
commercial trading more efficient and allowing for
higher awareness on the part of consumers. Moreover,
with regard to obtaining measurements, even on the
basis of images, it is necessary to have metrological
rigor, which means having knowledge of the variables
involved and of their contribution to error, and also to
ensure that the process is replicable and that its results
may be repeated, with measurements which are
known and controlled within specific ranges. In this
light, closer attention is needed to the standardization
of measurements, and a higher emphasis on
metrology in this sector becomes crucial, aiming to
ensure repeatability of the results and the
reproduction of the measurements employed, thus
improving the reliability of this technique.
Over the past few years, the explosive
growth in both computer hardware and software has
led to many significant advances in computer vision
technology. Computer vision technology provides a
high level of flexibility and repeatability at relatively
low cost. It also permits fairly high plant throughput
without compromising accuracy. Currently, computer
vision systems are being developed as an integral part
of food processing plants for on-line, real-time quality
evaluation and quality control (Gunasekaran.
S.,1996.).

For a typical application of computer vision
in the food industry, the key or core elements are the
visual meanings or descriptions of food products in
images (Ballard, D. A.,1982) which are known as
image features that are extracted from images as
indicators of food qualities. Images of food products
captured in a computer system are stored, processed,
and displayed in the form of matrices (the elements
are called pixels for image processing purpose) in
which information stored can be obtained as image
features.
III.
Image Processing
An image is an array, or a matrix, of square
pixels (picture elements) arranged in columns and
rows. Pixels are basic components of images. Two
kinds of information are contained in each pixel, i.e.
brightness value and locations in the coordinates that
are assigned to the images. The former is the color
feature while features extracted from the latter are
known as size or shape features. Image processing
systems play a more and more important role in the
food quality evaluation by maintaining accuracy and
consistency while eliminating the subjectivity of
manual inspections. They offer flexibility in
application and can be reasonable substitutes for the
human visual decision-making process. In order to
develop an automated system for food quality
evaluation, image processing techniques are often
combined with mechanical and instrumental devices
to replace human manipulative effort in the
performance of a given process. In such a system, the
image processing system is the centre, which controls
the operation of the machinery (Li, Q. Z., 2002).
Computer Vision System
Computer vision is the science that develops
the theoretical and algorithmic basis by which useful
information about an object or scene can be
automatically extracted and analyzed from an
observed image, image set or image sequence
(Haralick, R.M.,1992). An image is thus the core of
computer vision system and it can be defined as a
spatial representation of an object or scene. Computer
vision systems are being used increasingly in the food
industry for quality assurance purposes. Essentially,
such systems replace human inspectors for the
evaluation of a variety of quality attributes of raw and
prepared foods.
CVS has found many applications in
academic research and the food industries, ranging
from a simple quality evaluation of foods to a
complicated robot guidance application. In the last
decade, this technique has been successfully used in
color measurement analysis and quality inspection of
a great variety of foods, including product
classification or grading based on surface feature
detection and defect finding. Alternatively ,computer
vision system (CVS), a non destructive method,
offering objective measures for color and other
physical factors.

Matlab Toolbox
MATLAB (matrix laboratory) is a numerical
computing environment and fourth-generation
programming language. Developed by MathWorks,
MATLAB allows matrix manipulations, plotting of
functions and data, implementation of algorithms,
creation of user interfaces, and interfacing with
programs written in other languages, including C,
C++, Java, and Fortran. Although MATLAB is
intended primarily for numerical computing, an
optional toolbox uses the MuPAD symbolic engine,
allowing access to symbolic computing capabilities.
An additional package, Simulink, adds graphical
multi-domain simulation and Model-Based Design for
dynamic and embedded systems. In 2004, MATLAB
had around one million users across industry and
academia (Richard G., 2002) MATLAB users come
from various backgrounds of engineering, science,
and economics. MATLAB is widely used in academic
and research institutions as well as industrial
enterprise.

Artificial Neural Network
Artificial neural networks (ANNs) are
biologically inspired computer programs designed to

simulate the way in which the human brain processes
information. ANNs gather their knowledge by
detecting the patterns and relationships in data and
learn (or are trained) through experience, not from
programming. An ANN is formed from hundreds of
single units, artificial neurons or processing elements
(PE), connected with coefficients (weights), which
constitute the neural structure and are organised in
layers. The power of neural computations comes from
connecting neurons in a network. Each PE has
weighted inputs, transfer function and one output. The
behaviour of a neural network is determined by the
transfer functions of its neurons, by the learning rule,
and by the architecture itself. The weights are the
adjustable parameters and, in that sense, a neural
network is a parameterized system. The weighed sum
of the inputs constitutes the activation of the neuron.
The activation signal is passed through transfer
function to produce a single output of the neuron.
Transfer function introduces non-linearity to the
network. During training, the inter-unit connections
are optimized until the error in predictions is
minimized and the network reaches the specified level
of accuracy. Once the network is trained and tested it
can be given new input information to get output. A
typical ANN consists of input layer, hidden layer and
output layer. Input layer consists of your input values,
hidden layer consists of calculation parts with
involves multiplication of weights and addition of
bais, and output layer consist of the required ouput for
the given inputs.
Developing a neural network requires three phases:
the training or learning phase,
the recall phase (validation) and
the generalization phase (testing).
The training phase is the first phase where a
network is given various inputs and output, to train
the network in the form of a text file, so that network
will learn the inputs and their outputs. In the second
stage network is made to recall all the process and to
check its accuracy. If it showed 99% accuracy, then
no need of further training and if not then go back to
training phase again until 99% accuracy is achieved.
The last step is the testing setup in which we test the
pre-trained neural network (Traeger M, et al., 2003).
VI.
Computer Vision Setup
Computer vision system consists of following main
parts:
Lighting system
Digital camera and image acquisition
Image processing
(i) Lighting system: Sample whose image is to be
taken should be illuminated using two parallel lamps
(with two fluorescents tubes by lamp, TL-D Deluxe,
Natural Daylight, 18W/965, Philips, USA) with a
color temperature of 6500 K (D65, standard light
source commonly used in food research) and a colorrendering index (Ra) close to 95%. Both lamps (60
cm long) were situated 35 cm above the sample and at
www.ijera.com
www.ijera.com
an angle of 45º with the sample. Additionally, light
diffusers covering each lamp and electronic ballast
assured a uniform illumination system.
(ii) Digital camera and image acquisition: The
stage of image acquisition consists of capturing a real
image and transforming it into a digital image using
devices such as cameras, scanners, videos, etc. A
digital image is a numerical representation of an
image that can be computationally processed. A Color
Digital Camera (CDC), model used should be located
vertically over the background at a distance of 30 cm.
The angle between the camera lens and the lighting
source axis was approximately 45º, since the diffuse
reflections responsible for the color occurs to this
angle from the incident light (Francis and Clydesdale,
1975). Also, considering that ambient illumination is
very critical for reproducible imaging (Shahin and
Symons 2001), sample illuminators and the CDC
were covered with a black cloth to avoid the external
light and reflections. As standard capture conditions,
images were taken on a matte black background and
using the following camera settings: manual mode
with the lens aperture and speed, no zoom, no flash,
intermediate resolution of the CDC pixels, and
storage in JPEG format. The capture pictures should
be then transferred to PC with is loaded with the
image processing software.
(iii) Image processing: All the algorithms for
preprocessing of full images, segmentation from the
background, and color analysis were written in
MATLAB 6.5 (The MathWorks, Inc., USA). Preprocessing is the stage preceding the extraction of
characteristics, which aims at improving the acquired
image and highlighting the features or regions of
interest, thus removing distortions and noise while not
adding further information to its content. Preprocessing involves techniques to highlight regions
and details and to remove any noise which may
interfere in the analysis of objects and/or regions of
interest. In this context, there is a great variety of
techniques from which we can highlight the gray
scale and color transformation, as well as
thresholding and filtering (Koschan A., 2008). This is
an important stage in an automatic inspection system.
The segmentation process can be based on the
similarity of the color of each pixel and its
neighbouring pixels. Sometimes similar pixels, in
terms of color, are not part of the same object or
feature. The extraction of parameters enables the
association between regions of the image and objects
in the scene (Gonzalez RC., 2009). After these stages,
the image should be ready for the extraction of
important characteristics. The final stage—
processing—aims to recognize and interpret the
images, seeking to make sense of the set of objects of
the image, with the goal of improving human
visualization and the automatic perception of data in a
computer.

VII.
Calibration of the CVS
The standard RGB involves two parts: (i) the
viewing environment parameters, which are
recommended for viewing photographic images on
monitors, and (ii) the definitions and transformations
standard device space colorimetric which provide the
necessary transforms to convert between the RGB
color space and the L*a*b* color space (Stokes et al.,
1996). The camera zoom, resolution have to be
calibrated and this can be achieved by using some
www.ijera.com
standard reference chart or color chart (Fig 1.1)
whose RGB and L*a*b* values are know. The
camera calibration can be done by taking picture of
the color card in the image processing chamber and
extracting it RGB or L*a*b* values and matching of
values with the given values of color card. The
conditions were the values obtained from camera
come close to the value of color card, means the
camera and conditions are calibrated and these
settings should be recorded and used for further use.
Fig 1.1: Color card for calibration of CVS system.
VIII.
Feature extraction from images
According to the diverse information stored
in pixels, image features obtained can be categorized
into four types - color, size, shape, and texture (Du &
Sun, 2004a).
(i)Color: Color is the intensity of pixels, while size
reflects the number of pixels and shape describes the
boundary of food products.
(ii)Size and Shape: Size reflects the number of pixels
and shape describes the boundary of food products.
Size features are usually obtained using
measurements of area, perimeter, length, and width.
Shape is characterized mostly in two ways, i.e., size
dependent measurements such as compactness and
elongation, and size independent measurements such
as spatial moment and Fourier descriptor (boundary
shape).
(iii)Texture: Texture is normally the dependency
between pixels and their neighbouring pixels or the
variation of intensity of pixel. Texture is normally the
dependency between pixels and their neighbouring
pixels or the variation of intensity of pixels.
IX.
Application of CVS in Fruits and
Vegetables
www.ijera.com
Potato inspection on the basis of shape, size
and color, analysis of defects have been successful
achieved using CVS system. In 2010, Barnes et al.,
developed a new method of detecting defects in
potatoes using computational vision. In order to
reduce shadow effects and changing conditions of
illumination during image acquisition, the potatoes
have been placed inside a white cylinder, with
daylight lamps placed around the top of it, on a total
of 4 lamps. After the segmentation of the potato on
the bottom, a pixel classifier was trained to detect
spots using extraction of characteristics of the image.
Some parameters were used based on statistical
information extracted from color and texture of the
region surrounding the pixel, and then, an algorithm
was used to automatically sort spots and not spots.
The result showed that the method was able to
classify and optimize the performance of
classification with low computational cost, presenting
levels of accuracy for white and red potatoes of 89, 6
and 89, 5 %, respectively. Noordam,et. al., 2009 and
Cabrer, et. al., 2008 .analysed potatoes as a whole,
and, to this end, a camera with mirrors has been used
in order to obtain a global image.
CVS consists of an image acquisition set up,
digital image analysis and special sensory color chart
to classify objectively potato chips according to their
color in different categories. For this purpose, sensory
measurements of color in 100 potato chips were
1200 | P a g e

correlated with the corresponding objective
Potato chips with and without ruffles of
different brands were used for training and validation
experiments. Sensory evaluations done with a special
color chart classified potato chips in seven color
categories. Simultaneously, the color of the same
potato chips classified by the sensory panel, was
determined objectively by a computer vision system
in L*, a*, b* units. Color measured by the sensory
assessors was highly correlated with the color
determined objective in L*, a*, b* units by a CV
system (Franco, P., 2009).
Apples are very susceptible to damage and
the presence of bruises on the apple skin affects not
only the appearance of the apple, which is an
important indicator of quality, but also accelerates its
deterioration. Therefore, an effective system of
removing damaged apples allows the maintenance of
the quality of the other products in a tray, and it is one
of the essential stages in the processing of apples.
However, certain types of apples show a bicolored
characteristic, that is, they exhibit two colors on their
appearance, which makes their sorting in processing
very hard to meet European requirements with regard
to classification. According to Madieta , it is
necessary to know the interval in the color variation
of the apple skin in order to decide the best manner of
measuring it. Based on the type of color distribution
on the skin, the apple may be classified as
homogenous, heterogeneous or bicolored. In this way,
many studies are carried out with the goal of reaching
better performance of visual systems with a view to
meeting these requirements, seeking improvements in
the localization of defects (Madieta, E.,2003 and
Unay D., 2006)

TOOLBOX were used to detect and calculate external
appearance of an olive’s skin which is considered to
the most decisive factor in determining its quality as a
fruit. Seven commercial categories of olives,
established by product experts, were used:
undamaged olives, mussel-scale or ‘serpeta’, haildamaged or ‘granizo’, mill or ‘rehu´ s’, wrinkled
olive or ‘agostado’, purple olive and undefineddamage or ‘molestado’. The original images were
processed using segmentation, color parameters and
morphological features of the defects and the whole
fruits. The application of three consecutive
discriminant analyses resulted in the correct
classification of 97% and 75% of olives during
calibration and validation, respectively. However the
correct classification percentages vary greatly
depending on the categories, ranging 80–100% during
calibration and 38–100% during validation
(Riquelme, M T.,2008).
Visual features of raisins such as wrinkle
edge density, angularity, elongation for the purpose of
grading were analysed by computer vision (Okamura,
Dewiche, & Thompson, 1993). The developed system
accuracy was comparable to industrial standard air
stream sorter but poorer than sight grading results.
Sorting of strawberries based on shape and size was
performed using computer vision with accuracy of
98% reported for the developed system (Nagata, Cao,
Bato, Shrestha, & Kinoshita., 1997). Also CVS
system is used to detect the various defects in citrus
fruits (Fig 1.2).

Application of CVS in Cereals
Image processing was used to determine the
utility of morphological features for classifying
individual kernels of five varieties of barley. It was
found, that the method using morphological features
www.ijera.com
may be successfully employed in image analysis for a
preliminary varietal identification of barley kernels. It
was also shown that the data reduction considerably
improved the results of the classification of barley
kernels. Furthermore, linear discriminant analysis
(LDA) was found to be the method which best

separated different varieties of objects (Piotr,
Z.,2008).
Digital image analysis was used to monitor
baking process, in order to check and control quality
of baked goods. Industrial baking is a temperature and
time controlled process, which considers neither the
actual quality of the raw materials nor the process
parameters like humidity, pastry temperature and
actual pastry status. Furthermore the baking process is
irreversible. Digital image processing can be used to
make digital images of the baking goods from inside
the oven in a continuous form. The goal was the
development of algorithms for distinction of baking
goods and characterization of color saturation and
shape, altogether resulting in an optical online process
monitoring system (Paquet, D.O.,2011).
Combination of digital image from digital
camera, computer and vision builder have good

potential to be used for color measurement and this
technique can provide color information such as for
parboiled rice compared to a color measuring
instrument (Bin Lv, et al., 2009). It has provided a
less expensive and more versatile technique to
determine the surface color of parboiled rice
compared to instrumental color measurement.
Quality characteristics of corn have also
been investigated by the use of computer vision. The
classification of germplasms (ear of corn) was
performed by use of an algorithm developed to
discriminate round-shaped samples (Panigrahia,
Misrab, &Willsonc, 1998). A discrimination was
done between cylindrical and noncylindrical
germplasms with an overall accuracy of 82.5% for
this classification (Fig 1.3)

Application in Animal Products
Visual inspection is used extensively for the
quality assessment of meat products applied to
processes from the initial grading through to
consumer purchases. (McDonald and Chen.,1990)
investigated the possibility of using image-based beef
grading in some of the earliest studies in this area.
They discriminated between fat and lean in
longissimus dorsi muscle based on reflectance
characteristics, however poor results were reported.
Recently greater accuracy was found in a study by
(Gerrard et al.,1996) where R2 (correlation
coefficient) values of 0.86 and 0.84 for predicted lean
color and marbling were recorded, respectively, for
60 steaks using image analysis. (Li et al.,1997)
measured image texture as a means of predicting beef
tenderness. Color, marbling and textural features were
extracted from beef images and analysed using
statistical regression and neural networks. Their
findings indicated that textural features were a good
indicator of tenderness. Image analysis was also used
for the classification of muscle type, breed and age of
www.ijera.com
bovine meat (Basset, Buquet, Abouelkaram,
Delachartre, & Culioli., 2000).
A technique for the spectral image
characterisation of poultry carcasses for separating
tumourous, bruised and skin torn carcasses from
normal carcasses was investigated by Park, Chen,
Nguyen, and Hwang (1996). Carcasses were scanned
by an intensified multi-spectral camera with various
wavelength filters (542–847 nm) with the results
indicating that the optical wavelengths of 542 and 700
nm were the most useful for the desired classification.
For separating tumourous carcasses from normal
ones, the neural network performed with 91%
accuracy.
Storbeck and Daan (2001) measured a
number of features of different fish species using an
image processing algorithm based on momentinvariants coupled with geometrical considerations
for discrimination between images of fish as they
passed on a conveyor belt at a speed of 0.21 m/s
perpendicular to the camera as shown in Fig. 1.4.

Other Applications
The tea quality depends upon a number of
physical attributes such as color, particle shape,
particle size and texture. Computer vision methods
have been found to be very helpful in quality
evaluation of tea. Using computer vision it has been
observed that the tea images contain some definite
patterns or texture due to different surface features of
tea granules. Image processing applications such as
classification, detection and segmentation of images
could be applied optimally to determine these
parameters. The color development of tea during
fermentation can be determined using CVS system
(Gill, G. S., 2011).
Fig. 1.5: Development of color and quality during fermentation.
Computer vision can be successfully used
for the assessment of pizza topping quality. Three
different indexes were used to quantify the quality of
the toppings examined i.e whole pizza, mushroom
and ham toppings. New styles of pizza are being
produced in this highly competitive market all the
time. Among them, topping percentage and
distribution are the key parameters of pizza quality
and CVS has proved to be reliable method for
determining Pizza quality.

A comparison was made with the CVS read
L* a* b* values and huntercolorlab. An excellent
correlation was found between a* values from the
CVS and from the Hunterlab (R2= 0.97). But L* and
b* values, the correlation coefficients were smaller
(R2= 0.80).This difference between both color
systems may be largely due to the fact that
measurements with the colorimeter do not extend
over the whole surface.
