【Abstract】 Edge detection is a basic and important subject in computer vision and image measuring. In this paper, some typical edge detection algorithms are compared in the application of non-touching measurement of subminiature accessory. The methods are put forward to pick up the edge of subminiature accessory by combining image partition algorithms with outline trace algorithms. At last, the above algorithms obtain comparison with the practical images.更多还原
