Vector-valued color image edge detection using Green function approach

In this paper, an extended version of differential equations is introduced on the concept of edge detection methods for color images based on the correlation of R, G, and B components. To obtain the color edge detection operator, the Green´s function approach is used to derive the obtained differential equation. The proposed color edge detection method is compared with other color edge detection methods on the several test images. The experimental results show the feasibility of the proposed approach.
