Complex shearlets and rotary phase congruence tensor for corner detection

作者：

Highlights：

• Proposed complex shearlets can overcome the weakness of the current shearlets.

• Idea fully using both amplitude and phase information to detect corners is novel.

• A new phase congruence model with high localization ability and noise tolerance.

• A new rotation-normalized tensor using all amplitudes and phases to detect corners.

• The work yields improvements on the current state-of-the-art in corner detection.
