Corner Detection Based on Shearlet Transform and Multi-directional Structure Tensor

•It took full advantages of shearlet to obtain structural information.•Improved shearlets to overcome the weakness of the current shearlets for corner detection.•A novel multi-directional structure tensor for making full use of structural information.•A new multi-scale corner measurement function for exactly refining candidate corners.•It yields some improvements on the current state-of-the-art in corner detection.
