Noise robust image edge detection based upon the automatic anisotropic Gaussian kernels

作者：

Highlights：

• The reasons why some obvious edge miss detected in Canny detector are analyzed thoroughly.

• The automatic anisotropic Gaussian kernels are designed and a revised edge extraction is proposed.

• A noise robust edge detector with excellent performance is presented.
