This function OPENSURF, is an implementation of SURF (Speeded Up Robust Features). SURF will detect landmark points in an image, and describe the points by a vector which is robust against (a little bit) rotation ,scaling and noise. It can be used in the same way as SIFT (Scale-invariant feature transform) which is patented. Thus to align (register) two or more images based on corresponding points (see example3.m), or make 3D reconstructions. This Matlab implementation of Surf is a Matlab optimized translation of the OpenSurf C# code of Chris Evans, and gives exactly the same answer. ...
