Rathod, Bhavesh Tanawal, Vatsal Shah Computer Engineering, Gujarat Technical Univesity, BVM, V.V.nagar, dist.Anand, Gujarat, India Abstract— In agriculture research of automatic leaf disease detection is essential research topic as it may prove benefits in monitoring large fields of crops, and thus automatically detect symptoms of disease as soon as they appear on plant leaves. The term disease is usually used only for destruction of live plants. This paper provides various methods used to study of leaf disease detection using image processing. The methods studies are for increasing throughput and reduction subjectiveness arising from human experts in detecting the leaf disease[1].digital image processing is a technique used for enhancement of the image. To improve agricultural products automatic detection of symptoms is beneficial. Keyword— Leaf disease, Image processing. I. INTRODUCTION India is an agricultural country. Farmers have wide range of diversity to select suitable fruit and vegetable crop. Research work develops the advance computing system to identify the diseases using infected images of various leaf spots. Images are captured by digital camera mobile and processed using image growing, then the part of the leaf sport has been used for the classification purpose of the train and test. The technique evolved into the system is both Image processing techniques and advance computing techniques. Image Analysis Can Be Applied For The Following Purposes: 1. To detect diseased leaf, stem, fruit. 2. To quantify affected area by disease. 3. To find the boundaries of the affected area. 4. To determine the color of the affected area. 5. To determine size & shape of leaf. 6. To identify the Object correctly. Etc. Fig. 1. Image analysis. Disease management is a challenging task. Mostly diseases are seen on the leaves or stems of the plant. Precise quantification of these visually observed diseases, pests, traits has not studied yet because of the complexity of visual patterns. Hence there has been increasing demand for more specific and sophisticated image pattern understanding [1]. Various Types Of Leaf Spot Deseases: – Bacterial – Fungal – Viral
