Investigation on Image Edge Detection Method of Pests in Stored Grain
储粮害虫图像边缘检测算法研究

The system structure of on-line detection method of pests in stored grain based on machine vision is discussed. The image edge detection method of pests in stored grain is very important part. The method of Roberts,Sobel, Krisch and Gauss-Laplace are analysed in image edge detection of pests in stored grain. These methods are investigated in VC++ 6.0. These methods and their applications in special image of pests in stored grain are compared at last.
