This algorithm identifies corners in and make corrrelations between two images.
- Smoothing the image using a Gaussian filter to reduce noise.
- Computing the image gradient to capture intensity changes.
- Calculating the autocorrelation matrix to analyze local gradient behavior.
- Applying a corner response measure to identify potential corners based on the matrix elements.
- Performing non-maximum suppression to eliminate weak corners and keep only the strongest ones.
- Selecting output corners based on a chosen strategy
