The detection method of pests in stored grain is always investigated. The method based on image recognition is often discussed. With development of computer technology, information processing, pattern recognition, intelligence detection, detection method based on image recognition develops fast and becomes main direction of grain pests intelligence detection. This paper puts forward an edge detection algorithm based on grey relation analysis.The importance of image's edge detection based on grey relation analysis in pests image processing is introduced. At first the reference series and compar...
