This code is to start experiments with global motion models. The corner detection can be either fast_9 or Harris. Corner matching is currently based on normalized correlation. Three flavors of ransac are used to estimate either a homography (8-param), or an affine model (6-param) or a rotation-zoom only affine model (4-param). The highest level API for the library is in vp9_global_motion.h, where there are two functions - one for computing a single model and another for computing multiple models up to a maximum number provided or until a desired inlier probability is achieved.
