Noise-robust color edge detector using gradient matrix and anisotropic Gaussian directional derivative matrix

作者：

Highlights：

• A color edge detector using gradient matrix and ANDD matrix is proposed.

• The SVD of the ANDD matrix is used to determine CESM and CESD of a color image.

• The new detector has both high edge resolution and noise-robustness.

• It attains better performance than the two existing color edge detectors.
