It will cost a lot of manpower and material resources to control the rice diseased due to the areas of rice cultivation and lacking of experts.
The practice shows the pest prevention science is an important measure to ensure that the rice harvest.
This paper mainly focuses on the research, design and implementation of the rice lesion recognition system. 1 General design The rice lesion recognition technology closely integrates the computer science and biological pathology which uses the inherent physiological characteristics of rice lesion for identification purposes[1-3].
