Domestic refrigerators are widely used household appliances and a large extent of energy is consumed by this system. A phase change material is a substances that can store or release significant amount of heat energy by changing the phase liquid to vapour or vice versa. So, reduction of temperature fluctuation and improvement of system performances is that main reason of using PCM enhances the heat transfer rate thus improves the COP of refrigeration as well as the quality frozen food. The release and storage rate of a refrigerator is depends upon the characteristics of refrigerators and its properties using phase change material for a certain thermal load it is found that COP of conventional refrigerator is increased . The phase change material used in chamber built manually and which surrounds the evaporator chamber of a conventional refrigerator the whole heat transfer for load given to refrigerator cabin (to evaporator) evaporator to phase change material by conduction. This system hence improves the performances of household refrigerator by increasing its compressor cut-off time and thereby minimizing electrical energy usage. The main objective is to improve the performance, cooling time period, storage capacity and to maintain the constant cooling effect for more time during power cut off hours using phase change material.

The fused image is evaluated using SSIM and ESSIM values, which indicate the proposed algorithm performs better fusion than previous methods.
Semi-Supervised Method of Multiple Object Segmentation with a Region Labeling...sipij
Efficient and efficient multiple object segmentation is an important task in computer vision and object recognition. In this work; we address a method to effectively discover a user’s concept when multiple objects of interest are involved in content based image retrieval. The proposed method incorporate a framework for multiple object retrieval using semi-supervised method of similar region merging and flood fill which models the spatial and appearance relations among image pixels. To improve the effectiveness of similarity based region merging we propose a new similarity based object retrieval. The users only need to roughly indicate the after which steps desired objects contour is obtained during the automatic merging of similar regions. A novel similarity based region merging mechanism is proposed to guide the merging process with the help of mean shift technique and objects detection using region labeling and flood fill. A region R is merged with its adjacent regions Q if Q has highest similarity with Q (using Bhattacharyya descriptor) among all Q’s adjacent regions. The proposed method automatically merges the regions that are initially segmented through mean shift technique, and then effectively extracts the object contour by merging all similar regions. Extensive experiments are performed on 12 object classes (224 images total) show promising results.

This document describes a proposed method for detecting and classifying brain tumors in MR brain images using robust principal component analysis (RPCA) and quad tree (QT) decomposition for image fusion. The method involves fusing T1 and T2 MRI images using RPCA and QT decomposition. The fused image is then segmented using level set segmentation. Features are extracted from the segmented image using complete local binary pattern (CLBP) and pyramid histogram of oriented gradients (PHOG) approaches. The features are then classified using an adaptive resonance theory (ART) classifier to classify the brain tumor as malignant or benign. The proposed method aims to efficiently fuse multi-modal MRI images for improved brain tumor detection and classification.

This document presents a hybrid methodology for classifying segmented images using both unsupervised and supervised classification techniques. The proposed methodology involves first segmenting the image into spectrally homogeneous regions using region growing segmentation. Then, a clustering algorithm is applied to the segmented regions for initial classification. Selected regions are used as training data for a supervised classification algorithm to further categorize the image. The hybrid approach combines the benefits of unsupervised clustering and supervised classification. The methodology is evaluated on natural and aerial images to compare its performance to existing seeded region growing and texture extraction segmentation methods.
Influence Analysis of Image Feature Selection TechniquesOver Deep Learning ModelIRJET Journal
This document discusses using different image feature selection techniques and their impact on deep learning models for image classification. It analyzes shape, color, texture, and combined features extracted from images using techniques like local binary patterns (LBP), grid color moments, and Sobel operators. A convolutional neural network (CNN) is used as the deep learning classifier. The performance is evaluated on a diabetic retinopathy detection dataset in terms of classification accuracy. The goal is to determine which feature selection techniques improve accuracy while minimizing computational resources when used with CNNs. A system is proposed that extracts individual features and combined features from images, then classifies them using CNNs to compare the impact of different feature selection approaches.

We presents a technique for moving objects extraction. There are several different approaches for moving object extraction, clustering is one of object extraction method with a stronger teorical foundation used in many applications. And need high performance in many extraction process of moving object. We compare K-Means and Self-Organizing Map method for extraction moving objects, for performance measurement of moving object extraction by applying MSE and PSNR. According to experimental result that the MSE value of K-Means is smaller than Self-Organizing Map. It is also that PSNR of K-Means is higher than Self-Organizing Map algorithm. The result proves that K-Means is a promising method to cluster pixels in moving objects extraction.

Image Binarization for the uses of Preprocessing to Detect Brain Abnormality ...Journal For Research
Computerized MR of brain image binarization for the uses of preprocessing of features extraction and brain abnormality identification of brain has been described. Binarization is used as intermediate steps of many MR of brain normal and abnormal tissues detection. One of the main problems of MRI binarization is that many pixels of brain part cannot be correctly binarized due to the extensive black background or the large variation in contrast between background and foreground of MRI. Proposed binarization determines a threshold value using mean, variance, standard deviation and entropy followed by a non-gamut enhancement that can overcome the binarization problem. The proposed binarization technique is extensively tested with a variety of MRI and generates good binarization with improved accuracy and reduced error.
A Research Paper on BFO and PSO Based Movie Recommendation System | J4RV4I1016Journal For Research
The objective of this work is to assess the utility of personalized recommendation system (PRS) in the field of movie recommendation using a new model based on neural network classification and hybrid optimization algorithm. We have used advantages of both the evolutionary optimization algorithms which are Particle swarm optimization (PSO) and Bacteria foraging optimization (BFO). In its implementation a NN classification model is used to obtain a movie recommendation which predict ratings of movie. Parameters or attributes on which movie ratings are dependent are supplied by user's demographic details and movie content information. The efficiency and accuracy of proposed method is verified by multiple experiments based on the Movie Lens benchmark dataset. Hybrid optimization algorithm selects best attributes from total supplied attributes of recommendation system and gives more accurate rating with less time taken. In present scenario movie database is becoming larger so we need an optimized recommendation system for better performance in terms of time and accuracy.
IoT based Digital Agriculture Monitoring System and Their Impact on Optimal U...Journal For Research
Although precision agriculture has been adopted in few countries, the greenhouse based modern agriculture industry in India still needs to be modernized with the involvement of technology for better production and cost control. In this paper we proposed a multifunction model for smart agriculture based on IoT. Due to variable atmospheric circumstances these conditions sometimes may vary from place to place in large farmhouse, which makes very difficult to maintain the uniform condition at all the places in the farmhouse manually. Soil and environment properties are sensed and periodically sent to cloud network through IoT. Analysis on cloud data is done for water requirement, total production and maintaining uniform environment conditions throughout greenhouse farm. Proposed model is beneficial for increase in agricultural production and for cost control and real time monitoring of farm.

A REVIEW ON DESIGN OF PUBLIC TRANSPORTATION SYSTEM IN CHANDRAPUR CITY | J4RV4...Journal For Research
As we know the population of Chandrapur City has increased so far in this years and with that has increased the vehicles causing high traffic volume & rise in pollution. But the transportation system in Chandrapur City is still the same. To reduce the traffic volume & pollution, we have to study & design the new transportation system in Chandrapur City. The system would be as similar to Nagpur City with the implementation of Star City Buses. In this Study we would first compare the speed of various vehicles. Collection of population details of Chandrapur City, approximate number of vehicles running on road, collection of data with respect to Ticket fares in Nagpur City- whether it is according to Kilometers or places to be reached, calculation of Ticket Fares for Chandrapur City on the basis data collected. By all these, the best mode of transport in City can be studied. On the basis of above data collected from various respected fields, we will then proceed for the Design part of urban transport system in Chandrapur City. For Design purpose, firstly we have to mark the centre of the City, when the centre is decided; we will then select the Bus Terminus. From centre of the city, we would prefer to select the routes of the Buses. One route will be for the city side like Jatpura Gate, Pathanpura Gate. One route will be for Ballarpur going road. The other one for Mul going road, then next for Nagpur road. We could decide as many routes once we get the clear idea about all data. By getting all this details, the next step is to design the destination points of Buses. Then we have to design about the Bus bays, to reduce congestion in the particular intersections or Stops of bus. After the design also can suggest for Bus lanes. Implementation of Bus Rapid Transit System (BRT system) is the main aim behind to develop transportation mode of City. The design of the Transport System can be designed with the help of various software’s like AutoCAD and Revit.

LABORATORY STUDY OF STRONG, MODERATE AND WEAK SANDSTONES | J4RV4I1012Journal For Research
Sandstones from seven different hydroelectric projects have been assessed to compare their water-related properties and engineering parameters and the comprehensive analysis has been presented. The study has been done by categorizing the sandstones in to three categories i.e. weak, moderate & strong sandstones. The study leads to four broad inferences: (1), there could be very large variation between two sandstones; e.g., here, sandstone S2, S4 & S5, vis-à-vis other two strong sandstones, is superior in all respects. (2), the four weak sandstones differ in respect of some – not all – properties and parameters. (3), none of the four weak sandstones is better than the other two in respect of all properties and parameters. (4), moderate sandstone shows higher values of shear strength parameters in comparison to all the sandstones (including stronger sandstones also) except S3 strong sandstone. In respect of individual properties, the grain density of all sandstones is similar, though their bulk densities, apparent porosity and water content show great variation. The weak, moderate and strong sandstones show qualitative difference in their uniaxial compressive strength and wave velocity (compression and shear, both); and the two are directly proportional. The study clearly demonstrates that there is no one-to-one correspondence between any two properties and parameters, but there is a diffused and/ or qualitative relationship between different sandstones, or certain properties and parameters of a particular variant.

Need of rice transplanting machine is growing nowadays because of unique feature seeding in well sequence and well manners. This will save too much efforts of human being. Class of people who uses this kind of machine is farmers and they are having poor economic background. To feed growing population is a huge challenge. Importation of rice will lead to drain out the economy of the country. Mechanization of paddy sector will lead to higher productivity with releasing of work force to other sectors. The objective of this project is to design a paddy transplanting mechanism to transplant paddy seedling by small scale farmers in the country. Hence, this is considered as an activity that needed mechanization. For mechanization the modeling and simulation evaluated for hand operated rice seeding machine, which is help the farmers to planting more and more amount of rice in good quality with low energy consumption and less harm to the environment. India is predominately an agricultural country with rice as one of its main food crop. It Produce about 80 million tons rice annually which is about 22% of the world rice production. Culturally transplanting of young seeding is preferred over direct seeding for better yield and better crop management practice. But this operation requires large amount of manpower (about 400 Man-Hour/ha) and task is very laborious involving working in stopping posture and moving in muddy field.

AN INTEGRATED APPROACH TO REDUCE INTRA CITY TRAFFIC AT COIMBATORE | J4RV4I1002Journal For Research
Coimbatore (11.0168°N,76.9558°E) is a fast developing cosmopolitan city with large number of industries and educational institutions. The development has lead to a large number of vehicles causing heavy traffic. The traffic congestion at Coimbatore has been a major problem which causes traffic jams and accidents. The major reason for traffic has been the mofussil buses that operate in the city. Around 1300 mofussil buses enter into the city, these buses play an important role in traffic congestion. The best solution is to construct a centralized bus stand at the outskirts of the city. This would reduce the traffic, accidents and also leads to development of the outskirts of the city. A suitable location near the city with sufficient road access to connecting cities has been chosen and the bus terminus has been designed, modeled with all facilities and features.

During past few years, brain tumor segmentation in CT has become an emergent research area in the field of medical imaging system. Brain tumor detection helps in finding the exact size and location of tumor. An efficient algorithm is proposed in this project for tumor detection based on segmentation and morphological operators. Firstly quality of scanned image is enhanced and then morphological operators are applied to detect the tumor in the scanned image. The problem with biopsy is that the patient has to be hospitalized and also the results (around 15%) give false negative. Scan images are read by radiologist but it's a subjective analysis which requires more experience. In the proposed work we segment the renal region and then classify the tumors as benign or malignant by using ANFIS, which is a non-invasive automated process. This approach reduces the waiting time of the patient.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Abstract
Domestic refrigerators are widely used household appliances and a large extent of energy is consumed by this system. A phase
change material is a substances that can store or release significant amount of heat energy by changing the phase liquid to vapour
or vice versa. So, reduction of temperature fluctuation and improvement of system performances is that main reason of using
PCM enhances the heat transfer rate thus improves the COP of refrigeration as well as the quality frozen food. The release and
storage rate of a refrigerator is depends upon the characteristics of refrigerators and its properties using phase change material for
a certain thermal load it is found that COP of conventional refrigerator is increased . The phase change material used in chamber
built manually and which surrounds the evaporator chamber of a conventional refrigerator the whole heat transfer for load given
to refrigerator cabin (to evaporator) evaporator to phase change material by conduction. This system hence improves the
performances of household refrigerator by increasing its compressor cut-off time and thereby minimizing electrical energy usage.
The main objective is to improve the performance, cooling time period, storage capacity and to maintain the constant cooling
effect for more time during power cut off hours using phase change material.
Keywords: Edge Detection, segmentation, classification, Object extraction and Object Detection
_______________________________________________________________________________________________________
I. INTRODUCTION
Object extraction is a challenging area in the image processing. In object extraction the technique of extracting objects from the
pre-processed image is done in such a way that similarity class within image is made into a number of clusters for isolating
segmented images from the original image. The nontrivial contents, usually in the form of interesting objects, are sufficient to
represent the semantic meanings in most cases and consequently play an important role in many image applications such as
content-based retrieval. Therefore, many methods have been proposed to automatically extract interesting objects. Image Object
extraction techniques are very useful for disease detection, object localization and object tracking. The method used for still
image object extraction can also use for 3D image and video frames for the same purpose. Object Extraction is a closely related
issue with the segmentation process. Image Segmentation is a process of dividing an image into sub partition based on some
characteristics like color, intensity etc.
The main goal of object extraction is to change the representation of an image into something more meaningful. To extract an
object from the image first we have to segment the entire image. User select the region as background and foreground by using
the markers and then the algorithm will segment the image and the foreground region will be extracted from the image. Image
segmentation is a fundamental step in many areas of computer vision including object recognition, video surveillance, face
recognition, fingerprint recognition etc. It provides additional information about the contents of an image by identifying edges
and regions of similar color and texture. Although a first step in high level computer vision tasks, there are many challenges to
ideal image segmentation. Segmentation subdivides an object into its constituent regions or objects. The level of detail to which
the subdivision is carried on depends on the problem being solved. That is the segmentation should stop when regions or objects
of interest have been detected. For example, if an image consists of a tree, the segmentation algorithm may either stop after
detecting the entire tree or further divide the tree into trunk and leaves.
Interactive image segmentation is a way to extract foreground objects in complex scenes using simple user interaction. The
key to success in interactive image segmentation is to preserve characteristics of the user’s interactive information and maintain
global data effectively.
II. REVIEW WORKS
Images contain different types of objects and structures which may convey information. counting involves estimating the number
of objects in an image, detecting involves presence the number of objects in an image. Counting arises in many real time
application such as counting grains in agriculture industry, counting cells in microscopic images, counting of number diamonds
in industry etc. Existing methods for counting involves a large amount of hardware which also adds to the cost or manual
counting which is time consuming and may give erroneous results [1-4]. In this paper image segmentation is stated as a vast
topic of research and choice of large number of researchers by the author. The reason for the popularity of image segmentation is
2. Object Detection, Extraction and Classification using Image Processing Technique

because of its importance in the area of image processing and computer vision. The prime task of the researchers working in the
field is to develop a method for efficient and better image segmentation. The segmentation done using approaches of clustering
are considered good for image segmentation. The advantage of using approaches of clustering in image segmentation is that this
is a wide area and can be employed in other areas of engineering too. In this paper the author has developed a new technique for
image segmentation keeping clustering as a base. K-mean algorithm is employed and distance parameter is considered for
deciding the performance. The distance measure „cosine‟ is employed in this paper. Sobel filter is then used for filtering and the
results are obtained using Marker Watershed algorithm. The performance parameters that are taken into consideration by the
author in this paper are Mean Square Error and PSNR [5-9]. In this paper the process of image segmentation is defined as the
technique via which we segment a given photograph into several parts in order that we can further analyzed every of these
components present in the photo. The author states that it is possible to extract some records via analyzing them and this statistics
is useful for excessive-stage gadget vision software. There are numerous techniques of photograph segmentation to be had in
literature. In this paper, analysis is done to examine the discontinuity-primarily based approach for photo segmentation. The
discontinuity-based totally segmentation may be categorised into 3 techniques: factor detection, line detection, and aspect
detection. The result of these numerous strategies is analyzed in MATLAB the use of IPT. The author additionally enforce the
unique part operators inclusive of Prewitt, Roberts, LoG, Canny and the consequences of these operators can be shown on
diverse pics[10-13]. In this paper the author offers a new method to picture segmentation the usage of Pillar okay-approach set of
rules and the algorithm defined using that set of rules is known as Pillar k-mean s algorithm. This segmentation method includes
a new mechanism for grouping the factors of high resolution pictures so that you can improve accuracy and decrease the
computation time. The system uses k-way for image segmentation optimized by means of the set of rules after Pillar. The Pillar
algorithm considers the location of pillars must be located as a long way from every other to face up to the pressure distribution
of a roof, as equal as the range of centroids between the information distribution. This set of rules is able to optimize the k-mean
clustering for photo segmentation in the aspects of accuracy and computation time. This set of rules distributes all initial
centroids in line with the most cumulative distance metric. In this paper a new technique for image segmentation is developed
that compares the results of K-mean algorithm with Gaussian aggregate model [4]. Experimental consequences make clear the
effectiveness of our approach to improve the segmentation satisfactory and accuracy factors of computing time . In this paper a
new histogram thresholding fuzzy C-method hybrid (HTFCM) approach is presented that would find distinct software in sample
popularity in addition to in laptop imaginative and prescient, particularly in shade photo segmentation. The histogram
thresholding approach that is proposed in the paper is employed to acquire all feasible uniform regions within the coloration
photograph. Then, the bushy C-manner algorithm is applied in the uniform regions while cluster formation and that will enhance
the compactness of formed clusters. Experimental outcomes have confirmed that the low complexity of the proposed HTFCM
technique should acquire better result[5].
III. PROPOSED METHOD
In this paper image processing using MATLAB commands are used to implement edge detection, segmentation, object detection
and object extraction of an image. For this problem, MATLAB graphical interface is used. Our aim is to accept an image from
user, then show its pixel value, convert it into grayscale and binary (black and white) image, also showing the pixel value of
grayscale image. Then enhancing the image. After that detect the edge of that image and based on it segment the image. After
segmentation detect the objects in the image and finally extract the objects from the image. These applications are also applicable
for medical images.
The stages in the methodology are shown below:
The steps involve in this methodology are describe below:
Accept Image (From User):
In this step, users are free to accept any type of image for performing the above next steps. It support file format JPG (.jpg) only.
The input image must be in RGB format. The input RGB image consists of the matrices of same size, representing the red green
3. Object Detection, Extraction and Classification using Image Processing Technique

and blue color of the image. This matrices are also says that how much color of each channel (red, green, blue) are used in the
image.
Converting into Greyscale:
Grayscale images consists of color grey, which consists different shades between black and white. After accepting input image
then converting it into greyscale represented a luminance image. It also creates the three matrices of red, green and blue channels
using linear intensity encoding by gamma expansion.
Converting into Binary:
Binary Image means an image only contains black and white color, it only assign two-pixel intensity value 0 and 1. It also called
monochromatic color. When an input image is converting into binary images, then it creates an image, which only consists of
black and white color. The value of three matrices corresponding red, green, and blue color is 0 (for black) and 1 (for white).
Image Enhancing:
There are two kinds of techniques used here for enhancing the image 1) Contrast stretching & 2) Histogram equalization. For
applying this method must convert the input image into grey image. The above techniques are only works on grey images.
In contrast stretching technique the intensity of an image is span to a desired range of values.
In histogram equalization technique the intensity of the image is adjust in such a way that it enhance the image contrast.
Edge Detection:
In edge detection technique, it finds the edges of the image based on the local maxima. First, convert the original RGB image
into greyscale image. Then filtering the all three color channel and resize the image. Then extracting the histogram values of the
filtering and try to find the local maxima based of the light reflection of the greyscale image pixel by pixel. After that finding the
local maxima, sort them and eliminate maxima value of certain range. Then using method multithresh(A,N) which
returns thresh a 1-by-N vector containing N threshold values using Otsu's method and use an input argument to imquantize to
convert image into an image with N + 1 discrete levels. After that, we get the edges of the whole image without any noise.
Segmentation:
Segmentation is an operation that partitioned an image into its component or it separate the objects. For segmentation edge
detection and thresholding is very important. After accepting, the input image from user must convert it into the greyscale image
and then for thresholding first consider a certain value in between 0 to 1 of each color channel (red, green and blue). Then
convert each channel into binary image and take the sum of three channel. Then complement the sum channel. Complement
means it convert the white space into black and vice versa, if there have any small holes then fill it with Ifill command.
Object Detection:
Object detection means determine how many objects are present in an image. So for this after segmented the input image find the
morphological structure of the input image, and then open the morphological image in greyscale mode. After that, find the area
and eccentricity of the all segmented areas and label them as well as bounded the all-region based on the connectivity with a
colourful bound box. After bounding all the objects count how many objects are in the input image.
Object Extraction:
Object Extraction means after segmentation and object detection just extracted all the objects from the images and show them all
individually. For this, after bounded all the regions label them. After labelling all the regions, find how many regions are present
in the images. After that using a loop for collecting or retrieving the objects from images. Here all the object images are in
greyscale mode.
For Medical Image:
Medical images are special images, they are RGB image but it’s not color image. Therefore, for thresholding it has not needed to
thresholding each color channel. Here consider a certain thresholding value, check the grey value of the image is greater than the
threshold value or not. Then take complement it, segment it, give boundary of the objects, and extract them.
