A Survey on Plant Leaf Disease Identification Techniques

Abstract

                         Agricultural productivity is the prime factor on which Indian Economy highly depends. As India is a developing nation, the increasing population majorly depends on the agricultural yield and its harvest. One of the main reasons for the reduction in plant growth is due to the various infectious plant leaf diseases. If proper attention is not given, it creates serious effects on the grade and quantity of the agricultural crops and also drastically declines the production rate. Most of the farmers still follow the manual methods for disease identification. This process is more time consuming and leads to earlier destruction of plants. Hence, image processing techniques can be deployed to eradicate these effects at the earlier stage itself. By using real time computer vision based systems, the various plant leaf diseases can be identified accurately. In this survey paper, several types of plant leaf diseases and its detection mechanisms are discussed briefly.
