Intuitively Understanding Harris Corner Detector

The author acknowledges that the Harris corner detection algorithm can be difficult to understand due to its complex process. However, they present a simpler way to comprehend the algorithm. By considering corners as connections of edges moving in different directions, the author explains how the algorithm works step by step. They provide code snippets and visualizations to demonstrate each stage, including finding the gradient of the image, suppressing corners, and thresholding the results. The author emphasizes that their implementation is equivalent to other implementations of the algorithm. This approach allows readers to grasp the algorithm without delving into advanced concepts such as Taylor series approximation or fitting ellipses.
