This is a MATLAB implementation for Harris corner detector and edge detector based on sobel kernel. It partially referred to the implementation of OpenCV, and see this tutorial for more details.
- method of Harris
- method of Shi-Tomasi
- non-maximum suppression
- subpixel accuracy
- immune to corner clustering
Prerequisite: matlab 2014b or higher.
