Ransac algorithm code
Webb5 aug. 2024 · Algorithm 2 shows steps of the RANSAC algorithm. We initially pick four non-collinear feature pairs randomly to compute a homography from these four pairs, and then test the goodness of this homography, by checking whether the number of good matches is consistent with this homography or not. WebbRANSAC Algorithm Basic idea: Try on a few different fits and choose the best one! The following stages will be followed. The method will be terminated if the model …
