Evaluation of Foliar Diseases using Image Processing

Image processing in the field of agriculture proves to be an innovative and emergent technology, which leads to incorporating the advanced techniques to enrich the farm input and output in a profitable and environment sensible manner. Present study has been intended to focus on various methods that use digital image processing technique to identify, quantify and classify foliar diseases of various crop plants. The existing issues related to leaf diseases that occurred on various crop plants have been assessed and reported. Based on the existing literature a sequential generalized process has been suggested for foliar disease. A comparison has also been drawn based on the visual analysis and image processing.
