Pattern Recognition Using Image Processing

Paddy cultivation plays an important role in agriculture. But the growth of crop is affected by various diseases. If detection of disease is not properly done at earlier stage, then it may result in decrease of paddy production. India is agriculture based country and it provides employment to peoples in rural areas.. The agricultural sector plays major role in development of our economy by providing employment for rural peoples. Paddy is the staple food of Indians and hence it is considered as nation’s important product. Crop management is followed to protect paddy plants from fungal and bacterial diseases. The main goal is to develop an image processing system to identify and classify the various diseases affecting the growth of paddy plants. The work is divided into two parts paddy crop disease detection and recognition of paddy crop diseases. Disease detection technique is used to detect the disease affected portion in the paddy plant. The techniques used to detect diseased portions of paddy crop are Boundary localization and Haar-like features methods and neural network is employed based on diseases classification.
