An automated approach for classification of plant diseases towards development of futuristic Decision Support System in Indian perspective

Abstract

The major cause for decrease in the quality and amount of agricultural productivity is plant diseases. Farmers encounter great difficulties in detecting and controlling plant diseases. Thus, it is of great importance to diagnose the plant diseases at early stages so that appropriate and timely action can be taken by the farmers to avoid further losses.The project focuses on the approach based on image processing for detection of diseases of soybean plants. The soybean images are captured using mobile camera having resolution greater than 2 mega pixels. The purpose of the proposed project is to provide inputs for the Decision Support System (DSS), which is developed for providing advice to the farmers as and when require over mobile internet. Our proposed work classifies the images of soybean leaves as healthy and diseased using Support Vector Machine (SVM). The algorithm comprises of four major steps: image acquisition, extracting the leaf from complex background, statistical analysis and classification. The pre-processing step includes conversion from RGB to HSV (Hue Saturation Value) color space. For extracting the region of interest (ROI) from the original image, multithresholding is used. The color based and cluster based methods are used for segmentation. The algorithm uses Scale Invariant Feature Transform (SIFT) technique which automatically recognizes the plant species based on the leaf shape. The SVM classifier proves its ability in automatic and accurate classification of images. Finally, it can be concluded from the experimental results that this approach can classify the leaves with an average accuracy of 93.79%. The proposed system will enable the farmers to get advice from the agricultural experts with minimal efforts.

Design for the methodology of plant leaf disease detection using image processing

“…Kutty et al [8] has used the neural network based system to classify the watermelon leaf diseases of Downey Mildew and Anthracnose. This classification is based on the color feature extraction from RGB color model.In this paper, we are using image processing technique for the detection of plant leaf diseases.…”

Disease Detection in Plant using Artificial Neural Network

“…Yogesh Dandwate et al [12] developed an "automated method for classification of plant malady towards the improvement of futuristic decision support system in Indian perception". Researchers discuss a method for identification of malady of soybean plants (dataset 120) color b and cluster-based technique is used for segmentation.…”

Implementation of Digital Signal Processing for Monitoring Plant Health

“…Various techniques of image processing are used for correctly identifying and classifying the diseases of plants. Paper [4] proposes the classification of plant diseases by using the technique of image processing that uses SVM classifier for discriminating healthy and diseased soybean leaves. Different mobile cameras were used in different farms and a database of 120 images is prepared for testing the algorithm.…”
