Color image edge detection based on information quantity of color triangle

Abstract

Abstract: In this paper, it proposes a method using a triangle area to detect changes in the color image edge, it can take full advantage of each color component of each pixel in the color image, and the vector metric of a color will be transformed into a scalar measure. Compared with the traditional edge detection algorithm, the edge detected by this method is relatively clear, and it can improve the accuracy of edge detection too.
