Implementation of Harris corner detection algorithm for feature point extraction, feature matching between two images, and final image stitching using MATLAB
The Harris algorithm is a corner detection method that identifies invariant feature points in images, significantly reducing computational load and accelerating processing speed. However, this approach leads to substantial information loss. The RANSAC (Random Sample Consensus) algorithm calculates mathematical models from point sets, effectively eliminating mismatched Harris corners to produce more authentic and accurate matching results.
The most intuitive explanation of Harris corner detection is: points that exhibit significant changes in any two mutually perpendicular directions. This algorithm was originally proposed by Harris in the paper "A combined corner and edge detector." Implementation-wise, it calculates the gradient covariance matrix and uses the corner response function to identify key points.
