The function harris_affine is for detecting the affine invariant interest points in an image and the harris_laplace is for detecting the scale invariant interest points.
Read an image in a variable "img" and call the function as "affine_invariant_points = harrisaffine(img,scaleinvpts)" for affine invariant points and "scale_invariant_points = harrisLaplace(img)" for scale invariant points.
The other functions are supporting functions used in harrisaffine.m for making the code shorter.
