This document reviews research on classifying crops from remotely sensed images. It discusses how multispectral and hyperspectral imagery have been used with both supervised and unsupervised classification techniques. Multispectral imagery provides good information for overall vegetation mapping but has limitations differentiating similar crops. Hyperspectral imagery can help overcome these limitations by identifying fine spectral differences. The document also discusses how microwave remote sensing, which is unaffected by clouds, can complement optical imagery by improving classification accuracy when data is fused. Overall, the review finds that remote sensing is useful for crop monitoring but challenges remain in identifying multiple crop types and differentiating similar crops.

Texture based weed classification has played an important role in agricultural applications. In the recent years weed classification based on wavelet transform is an effective method. But the feature extraction is main issue for proper classification of weed species. In this paper, the issue of statistical and texture
classification based on wavelet transform has been analysed. The efficient texture feature extraction
methods are developed for weed discrimination. Three group feature vector can be constructed by the mean
and standard deviation of the wavelet statistical features (WSF), Texture feature as Contrast, Cluster
Shade, Cluster Prominence and Local Homogeneity (WCSPH) and Energy, Correlation, Cluster Shade,
Cluster Prominence and Entropy features (WECSPE) which are derived from the sub-bands of the wavelet
decomposition and are used for classification. Experimental results show that Rbio33 Wavelet with
WECSPE texture feature obtaining high degree of success rate in classification.
Agriculture is the backbone of human sustenance on this world. Now a days with growing population we need the productivity of the agriculture to be increased a lot to meet the demands. In olden days they used natural methods to increase the productivity, such as using the cow dung as a fertilizer in the fields. That resulted increase in the productivity enough to meet the requirements of the population. But later people started thinking of earning more profits by getting more outcome. So, there came a revolution called “Green Revolution”. In this paper we implemented image processing using MATLAB to detect the weed areas in an image we took from the fields.

Identifying Citronella Plants From UAV Imagery Using Support Vector MachineTELKOMNIKA JOURNAL
High-resolution imagery taken from Unmanned Aerial Vehicle (UAV) is now often used as an
alternative in monitoring the agronomic plants compared to satellite imagery. This paper presents a
method to identify Citronella among other plants based on UAV imagery. The method utilizes Support
Vector Machine (SVM) to classify Citronella among other plants according to the extraction of texture
feature. The implementation of the method was evaluated using two group of datasets: 1) consists of
Citronella, Kaffir Lime, other green plants, vacant soil, and buildings, and 2) consists of Citronella and
paddy rice plants. The evaluation results show that the proposed method can identify Citronella on the first
group of datasets with an accuracy 94.23% and Kappa value 88.48%, whereas on the second group of
datasets with an accuracy 100% and Kappa value 100%.

Plant Leaf Disease Analysis using Image Processing Technique with Modified SV...Tarun Kumar
In this computing era, image processing has
spread its wings in human life upto the extent that image
has become an integral part of their life. There are various
applications of image processing in the field of commerce,
engineering, graphic design, journalism, architecture and
historical research. In this research work, Image
processing is considered for the analysis of plant leaf
diseases. Plant leaf diseases can be detected based on the
disease symptoms. Here, dataset of disease affected leaves
is considered for experimentation. This dataset contains
the plant leaves suffered from the
AlternariaAlternata,Cercospora Leaf Spot, Anthracnose
andBacterial Blight along with some healthy leaf images.
For this analysis, an autonomous approach of modified
SVM-CS is introduces. Here, concept of cuckoo search is
considered to optimize the classification parameters. These
parameters further help to find more accurate solutions.
This autonomous approach also extracts the healthy
portion and disease affected leaf portion along with the
accuracy of results.
Soil Classification Using Image Processing and Modified SVM Classifierijtsrd
Recently the use of soil classification has gained more and more importance and recent direction in research works indicates that image classification of images for soil information is the preferred choice. Various methods for image classification have been developed based on different theories or models. In this study, three of these methods Maximum Likelihood classification MLC , Sub pixel classification SP and Support Vector machine SVM are used to classify a soil image into seven soil classes and the results compared. MLC and SVM are hard classification methods but SP is a soft classification. Hardening of soft classifications for accuracy determination leads to loss of information and the accuracy may not necessary represent the strength of class membership. Therefore, in the comparison of the methods, the top 20 compositions per soil class of the SP were used instead. Results from the classification, indicated that output from SP was generally poor although it performs well with soils such as forest that are homogeneous in character. Of the two hard classifiers, SVM gave a better output than MLC.

Assessing mangrove deforestation using pixel-based image: a machine learning ...journalBEEI
Mangrove is one of the most productive global forest ecosystems and unique in linking terrestrial and marine environment. This study aims to clarify and understand artificial intelligence (AI) adoption in remote sensing mangrove forests. The performance of machine learning algorithms such as random forest (RF), support vector machine (SVM), decision tree (DT), and object-based nearest neighbors (NN) algorithms were used in this study to automatically classify mangrove forests using orthophotography and applying an object-based approach to examine three features (tree cover loss, above-ground carbon dioxide (CO2) emissions, and above-ground biomass loss). SVM with a radial basis function was used to classify the remainder of the images, resulting in an overall accuracy of 96.83%. Precision and recall reached 93.33 and 96%, respectively. RF performed better than other algorithms where there is no orthophotography.
AN ANALYSIS OF SURFACE AND GROWTH DIFFERENCES IN PLANTS OF DIFFERENT STAGES U...ijcseit
Genomes are main reason for growth and surface differences in the plants. All plants grow on basis of their different surrounding like soil, water, breed of seed, and climatic session. This paper attempts to find stem growth from birth to maturity level of selected plant using image processing technique. Few reasons have been observed commonly by the researchers that some plants could not grow sufficiently as to the other plants of similar breed and age. Images were taken of different stage of bean plant and images of some other plant samples were also included for better assessment. Researchers are trying to understand through their calculative analysis by image processing emulator in MATLAB to view its reasons. Suitable comparison technique is applied to detect their period of growth. Image processing methods like Restoration, stem or leaves spots, filtering, and plant comparison have applied in MATLAB. Those effects that are not supporting to grow the plants of their similar age group are matter to calculate scientifically later in the future. The observation would help for further support in medicinal science or agricultural science of plant and Bio-chemical.

focused on uncertainty analysis in the produced land-cover maps .we proposed an efficient technique for
classifying the multispectral satellite images using Support Vector Machine (SVM) into road area, building area
and green area. We carried out classification in three modules namely (a) Preprocessing using Gaussian
filtering and conversion from conversion of RGB to Lab color space image (b) object segmentation using
proposed Cluster repulsion based kernel Fuzzy C- Means (FCM) and (c) classification using one-to-many SVM
classifier. The goal of this research is to provide the efficiency in classification of satellite images using the
object-based image analysis. The proposed work is evaluated using the satellite images and the accuracy of the
proposed work is compared to FCM based classification. The results showed that the proposed technique has
achieved better results reaching an accuracy of 79%, 84%, 81% and 97.9% for road, tree, building and vehicle
classification respectively.

In the present growth of sensor technology is to improve the new chance and applications in GIS. This enhances the technology law a new method that should not focus on real time available products, but it must automatically lead to new ones. The aim of the paper is to make a maximum use of remote sensing data and GIS techniques to access land use and land cover classification in the Kiliyar sub basin sector in palar river of northen part of Tamil Nadu.IRS P6 LISS III is merged data to perform the classification using ERDAS Imaging. The RGB and L base supervised classification was based up on a Multispectral analysis, land use and land cover information‟s (maps and existing reports), which involves advanced technology and complex data processing to find detailed imagery in the study region. Ground surface reflects more radar energy emitted by the sensor from the study region, which makes it easy to distinguish between the water body, hilly, agriculture, settlement and wetland.
Automatic traffic light controller for emergency vehicle using peripheral int...IJECEIAES
Traffic lights play such important role in traffic management to control the traffic on the road. Situation at traffic light area is getting worse especially in the event of emergency cases. During traffic congestion, it is difficult for emergency vehicle to cross the road which involves many junctions. This situation leads to unsafe conditions which may cause accident. An Automatic Traffic Light Controller for Emergency Vehicle is designed and developed to help emergency vehicle crossing the road at traffic light junction during emergency situation. This project used Peripheral Interface Controller (PIC) to program a priority-based traffic light controller for emergency vehicle. During emergency cases, emergency vehicle like ambulance can trigger the traffic light signal to change from red to green in order to make clearance for its path automatically. Using Radio Frequency (RF) the traffic light operation will turn back to normal when the ambulance finishes crossing the road. Result showed the design is capable to response within the range of 55 meters. This project was successfully designed, implemented and tested.
Hyperspectral object classification using hybrid spectral-spatial fusion and ...IJECEIAES
Because of its spectral-spatial and temporal resolution of greater areas, hyperspectral imaging (HSI) has found widespread application in the field of object classification. The HSI is typically used to accurately determine an object's physical characteristics as well as to locate related objects with appropriate spectral fingerprints. As a result, the HSI has been extensively applied to object identification in several fields, including surveillance, agricultural monitoring, environmental research, and precision agriculture. However, because of their enormous size, objects require a lot of time to classify; for this reason, both spectral and spatial feature fusion have been completed. The existing classification strategy leads to increased misclassification, and the feature fusion method is unable to preserve semantic object inherent features; This study addresses the research difficulties by introducing a hybrid spectral-spatial fusion (HSSF) technique to minimize feature size while maintaining object intrinsic qualities; Lastly, a soft-margins kernel is proposed for multi-layer deep support vector machine (MLDSVM) to reduce misclassification. The standard Indian pines dataset is used for the experiment, and the outcome demonstrates that the HSSF-MLDSVM model performs substantially better in terms of accuracy and Kappa coefficient.

Classification technique on remote sensing images is an effort taken to identify the class of each pixel based on the spectral characteristics of various channels. Traditional classifications such as Maximum Likelihood are based on statistical parameters such as standard deviation and mean, which have a probability model of each pixel in each class. While the object-based classification method, one of which is the Decision Trees, is based on rules for each class with mathematical functions. This study compares the Decision Trees and Maximum Likelihood algorithms for land cover classification in the Surabaya and Bangkalan areas using Landsat 8 data. This research begins with creating Regions of Interest (ROIs) and Rules on images with greater than and less than functions for Decision Trees. The ROIs test was carried out using the Separability Index and matching each class using the Confusion Matrix. The experimental results show that the accuracy value resulting from the Confusion Matrix calculation is 90.48%, with a Kappa Coefficient Value of 0.87. The Decision Trees method produces land cover nigher to the actual condition than the Maximum Likelihood method. The difference in the class distribution of the two ways is not significant. This study is limited because the validation uses manual interpretation results. Future research is expected to use the large-scale classification results from the relevant agencies to verify the classification results and use field data, larger samples of ROIs, and the use of high-resolution imagery in order to improve the classification results.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

ABSTRACT
Crops identification from remotely
sensed images is essential due to use of remote
sensing images as an input for agricultural &
economic planning by government & private
agencies, Available satellite sensors like AWIFS,
LISS (IRS series), SPOT 5 and also
LANDSAT,MODIS are good source of
multispectral data with different spatial
resolutions & Hyperion, Hy-Map, AVIRIS are
good source of hyper-spectral data. Expected
methodology for this work is selection of satellite
data, use of suitable method for classification and
checking the accuracy of classification, from last
four decades various Researcher has been
worked on this issues up to some extent but still
some challenges are there like multiple crops
identification, differentiation of crops of same
type this paper investigate the research work
done in this concern & critical analysis of that
work has been presented here. Multispectral &
hyper-spectral images contain spectral
information about the crops good soft computing
& analysis skills required to classify & identify
the class of interest from that datasets, various
researchers has been worked with supervised &
unsupervised classification along with hard
classifiers as well as soft computing techniques
like fuzzy C mean, support vector machine &
they found different results with different
datasets

I. INTRODUCTION
Remote sensing, particularly satellites offer
an immense source of data for studying spatial and
temporal variability of the environmental parameters
[1]. Remote sensing has shown great promise in
identifying the crops grown in agricultural land. The
resultant information has been found to be useful in
the prediction of crop production and of land use. It
is playing a significant role for crop classification,
crop health and yield assessment. Since the earliest
stages of crop classification with digital remote
sensing data, numerous approaches based on
applying supervised and unsupervised classification
techniques have been used to map geographic
distributions of crops with optical data and
Characterize cropping practices Hyper spectral data
contains hypercube with no of bands which also act
as a good source of information the smallest
bandwidth of the hyper-spectral data tells fine detail
about the crops internal contents, not only the
optical but also Microwave remote sensing playing a
good role for handling issues related to crops due to
its distinct features.
II. REMOTE SENSING FOR CROP
CLASSIFICATION
Classification is the process where we
convert multilayer input image in to single layer
thematic map, However, classifying remotely sensed
data into a thematic map remains a challenge
because many factors, such as the complexity of the
landscape in a study area, selected remotely sensed
data, and image-processing and classification
approaches, may affect the success of a
classification[2].Broadly there are two approaches
for classification that are supervised classification
and Unsupervised classification as shown in Fig.1
Unsupervised Classification is a clustering analysis
in which pixel are grouped into certain categories in
terms of the similarity in their spectral values, in this
analytical procedure all pixels in the input Data are
categorized into one of the groups specified by the
analyst beforehand. Prior to the classification the
image analyst does not have to know about scene or
covers to be produced During post processing each
spectral cluster get linked to meaningful Label
related to actual ground cover thus as shown in fig.1
in Unsupervised Classification analyst just give the
number of cluster & iteration then suitable
algorithms gives given no. of clusters for input
image, Supervised Classification is much more
complex than Unsupervised classification in that
Analyst should aware about ground cover Process of
supervised classification involve the selection of
appropriate band then Definition ofsignature for
training samples these signature formsfoundation for
the subsequent classification care must be taken in
their selection. Selection of quality training samples
requires knowledge of and understanding of the

properties of the Different ground features in the
satellite imagery [19].
Figure 1.General methodology for classification
of remotely sensed image(Supervised &
Unsupervised).
Visual interpretation during classification
is based on standard FCC (False Color Composite)
generated using green, red and near-IR bands
assigned blue, green and red colors respectively.
Each crop having their own distinct internal
structures, some crops may have similarities, and
due to distinctness of each crop they have different
spectral signatures it.is complicated to classify crops
with similar internal structure or similar reflectance
behavior in this case hyper-spectral imagery plays
important role to find the minute difference between
these spectrally similar crops
III. USE OF MULTISPECTRAL IMAGES
Multispectral remote sensing systems use
parallel sensor arrays that detect radiation in a small
number of broad wavelength bands The
multispectral airborne as well as satellite remote
sensing technologies have been utilized as a
widespread source for the purpose of remote
classification of vegetation [3]. Depending on
geographic area, crop diversity, field size, crop
phonology, and soil condition, different band ratios
of multispectral data and Classifications schemes
have been applied [4] Nelis 1986 for example, used
a maximum likelihood classification approach with
Landsat data to map irrigated crop area in the U.S.
High Plains. Further Priece in 1997 refined such
approaches, using a multi-date Landsat Thematic
Mapper (TM) dataset in southwest Kansas to map
crop distribution and USDA Conservation Reserve
Program (CRP) lands in an extensive irrigated area
[4]..Multi temporal data improve the accuracy of
classification SujayDatta et.al. have used LISS 1
Data for wheat crop classification by combining
January & February two dates data & deriving there
first two principle components they got 94 %
classification accuracy[5] . K.R.Manjunath
et.al(1998) have been worked on IRS LISS II &
LISS III for crops identification & conclude that
spatial resolution & spectral band selection are
affects on the classification results depending on
crops area[6]. S.P.Vyaset.al. have been used multi
date IRS LISS III data for multi crop identification
and crop area estimation in Utter Pradesh (India)[7],
They worked for mustard, potato & wheat crops
after performing classification and comparing the
result with single date classification results they
conclude that with the use of multi date IRS LISS
III data it was possible to discriminate & map the
various crops in the study area whereas single date
is still good for homogeneous area & reduce data
volume
I. P. B. C. Leiteat el(2008) has been worked on
Hidden Markov Model (HMM) based technique to
classify agricultural crops. They have used 12
Landsat images for 5 crop types, indicated a
remarkable superiority of the HMM-based method
over a mono temporal maximum likelihood
classification approach. And found 94% accuracy
similarly they conclude that HMM approach also
performed well to recognize phonological stages of
crops[8], Qiong An et al.(2009) have been use
adaptive feature selection model In his work for rice
crop with MODIS data the extracted spectral
characteristics are analyzed using statistical method
and dynamic changes of temporal series of indices
including NDVI, EVI, MSAVI and NDWI are
studied and by taking account of computational
complexity & time effectiveness of calculation the
Adaptive Feature selection model(AFSM) is studied
& he got 94 % accuracy which greater than general
classification by 3%[9], VijayaMusande et. al. have
been worked for Cotton crop discrimination using
fuzzy classifier approach in their work they have
used temporal AWIFS & LISS III data sets of
different months as per life cycle of cotton crops and
by generating indices like NDVI,TNDVI,SAVI &
TVI they got improved vegetation signal[10].
III. USE OF HYPER-SPECTRAL IMAGES
Hyper spectral remote sensing imagers
acquire many, very narrow, contiguous spectral
bands throughout the visible, near-infrared, mid-
infrared, and thermal infrared portions of the
electromagnetic spectrum as shown in Fig.2 Hyper
spectral data contains huge volumes so it is
complicated to classify crops from it with some
traditional classification techniques, The availability
of hyper spectral data has overcome the constraints
and limitations of low spectral and spatial resolution

conducted for six crops namely barley, wheat,
chickpea, lentil, vetch, and cumin by evaluating the
various indices based on two bands they have
chosen only 12 bands out of 430 which provide
optimal biophysical information about all 6
crops[11] some researcher proposed a procedure to
reduce Dimensionality of hyper spectral data while
preserving relevant information for posterior crop

&Sequential Floating Forward Selection algorithm
(HFFS) [12].Xiangrong Zhanget.al(2009) have
been worked for A new feature extraction method
based on immune clonal selection (ICSA) and PCA
for classification of Hyper-spectral remote sensing
image& they conclude that given method gives
better classification results[13].FaridMelganiandand
LorenzoBruzzone have used support vector machine
for hyper-spectral image classification (2004) and
they conclude that SVMs Are effective than Radial
based function neural networks and the K-nn
classifier in terms of classification accuracy,
computational time, and stability to parameter
setting. SVMs seem more effective than other
pattern recognition approach based onthe
combination of a feature extraction/selection
procedure and a conventional classifier, SVMs
exhibit low sensitivity to the Hughes phenomenon,
resulting in an excellent approach to avoid the
usually time-consuming phase required by any
feature-reduction method[14]Shwetanket al(2011)
have used EO 1 Hyperion data for rice crops
classification they have developed the spectral
library for rice crop and they performed supervised
classification with preprocessing & without
preprocessing, Preprocessing involves radiometric
correction, geometric correction and abnormal band
and pixels Detection and correction, they used
spectral angle mapper for classification & they got
86.96% accuracy for without preprocessed data and
89.33% accuracy for preprocessed data[15].
IV. USE OF MICROWAVE REMOTE SENSING
IMAGES
Microwave remote sensing, using
microwave radiation with wavelengths from about 1
Centimeters to a few tens of centimeters enable
observation in all type weather condition without
any restriction by cloud or rain. that’s why it can
penetrate through cloud cover, haze, dust, and all
but the heaviest rainfall,This is one of the
advantages which is not possible with visible &
infrared remote sensing, Microwave remote sensing
provides unique information for example sea wind
and wave direction which are derived from
frequency characteristics, Doppler’s effect,
Polarization, back scattering etc. that cannot be
observed by visible and infrared sensorsOptical
remote sensing is good source for crops
classification in spite of that its limitation due to
environmental interface like clouds which results
into scattering effect & we can’t get the fine details
from that images in that case Microwave Remote
sensing plays good role. Operating in microwave
region of the electromagnetic spectrum improves
signal penetration within vegetation & soil targets
the longer wavelength of the RADAR system are
not affected by cloud cover or haze, RADAR system
transmits microwave signal at specific wavelength
according to their design specification .Jesus Soria
Ruiz et.al.(2009) have been worked on corn
monitoring & crop yield using microwave & optical
remote sensing & conclude that integration of SAR
& optical data can improve the classification
accuracy[16], Jiali Shang et.al. (2010) have been
worked onMulti-temporal RADARSAT-2 and
TerraSAR-X SAR data for crop mapping in Canada
& they found that When multi-frequency SAR (X-
and C-band) are combined, classification accuracies
above 85% are achieved prior to the end of season
crops can be identified with accuracies between
86% (western Canada) and 91.4% (eastern
Canada)[17].
V. CONCLUSION
Remote sensing images are act as good
source for decision making related to crops
monitoring & mapping in optical remote sensing
multispectral images gives much detail for overall
vegetation mapping in large area whereas its having
limitation due broad wavelength & spatial resolution
we can’t differentiate crops of similar type in that
case hyperspectral images doing well, Selection of
spectral bands in hyperspectral images is also quite

challenging task whereas applying various hard as
well as soft classifiers gives good classification
results, some limitation of optical remote sensing
can be overcome by fusing optical remote sensing
images with microwave remote sensing images.
