A New Approach of Image Edge Detection Based on Sobel Operators and Grey Relation
一种基于Sobel算子和灰色关联度的图像边缘检测方法

A new approach to detect image edge using the Sobel operators and grey relation was brought forward, and then mechanism and algorithm were introduced. Simulation shows that this method has a high precision in image detection, a better antinoise ability and improving image detection effect.
