WebAffine invariant feature-based image matching. This sample is similar to feature_homography_demo.m, but uses the affine transformation space sampling technique, called ASIFT. While the original implementation is based on SIFT, you can try to use SURF or ORB detectors instead. Homography RANSAC is used to reject outliers.
