Contour-based corner detection via angle difference of principal directions of anisotropic Gaussian directional derivatives

作者：

Highlights：

• Anisotropic directional derivatives are applied to corner detection of images.

• A corner detector using the principal direction of the anisotropic directional derivatives is presented.

• The detector is compared with the three state-of-the-art corner detector.

• The detector behaves better in detection, localization, repeatability, and noise robustness.
