ABSTRACT
for the farmers, mall owners and scientists to identify the defected vegetables. The ancient human visual method and physical inspection methods are very expensive in time and money.
Here we develop an automated system to detect and assess the infection in vegetable using image. The specific objectives were to detect the disease and to evaluate the disease using image. With this technique diseased/infested and healthy vegetable images were collected like tomato brinjal. The aim of this paper to study the diseases in vegetable crops through Radon transforms technique by using diseased images. The specific objectives were used to detect and evaluate the diseases based on the images. In this study we have identified disease intensity, damaged percentage of the plant parts in Lycopersiconesculentum(tomato), Solanum tuberosum L. (Potato).Which are effected by a fungal disease “early blight” .The causative agent is Alternariaalternata. The symptoms were characterized by yellowing of leaves, stems and fruits at maturity they become brown and eventually drop from the plant.. This paper gives the essence data about asphalt defected location, assessment, order, pressure handle. Since the defected area have particular straight elements in the space area. It accepts the way that the pixels in defected area are brighter than their surroundings. The captured image is wavelet transformed asses the infected area.So detection of diseases is achieved by the two dimensional wavelet transform. Then the radon transform evaluate the defected area in the vegetable. Hence evaluation is achieved by the radon transform.

There is a huge number of man power need to the farmers, vegetable malls to identify, separate the defected vegetables. The ancient human visual and physical inspection methods were very expensive and also time and money taking methods. In this methods sometimes workers may not pay attention to identify the defected vegetables and they pack them along with the healthy vegetables this leads to the spoiling of major vegetables due to the organisms present in the defected area. To avoid this loss of vegetables an automated system was invented, it conducted so many experiments to identify the infected vegetables better than the other methods.
Key words: Wavelet transforms, Radon Transform
1. INTRODUCTION Most of the crops (Potato, Tomato) have been ruined due to the early blight diseases. This disease caused by a fungal organism Alternariaalternata. The symptoms were mainly appeared on the leaves, stems and fruits. A small yellow colour lessons form on the parts they enlarge finally they become brown and drop off from the plant when they were matured. This disease decreases the productivity and quality of the vegetables before and after harvesting.
In these methods the every person has to watch the all vegetables for the detection of disease. In some supermarkets and malls all vegetables are packed in cover with seal. Before packing the workers has to check all the vegetables individually. So this is a time consuming and laborious process. To overcome this physical involvement methods , So many experiments conducted for the invention of automated system.
The main reason and motivation for this paper is presented in the introduction. There is more labor involvement
