Harris corner detection

A very crude way to find corners in an image is to first find all the edges in the image and then pairwise check if the edges intersect. This might work well in some cases but will be very inefficient and impractical in real situations. Let us look at a faster corner detection algorithm—Harris corner.

Corners are considered as important points in an image. They are used in many applications such as image correlation, video stabilization, and 3D modeling. Harris corner is one of the most used techniques in corner detection. The Harris corner detector uses a sliding window over the image to calculate the variation in intensity. Since corners will have large variations in the intensity values around them, we are looking ...
