The first step searches a closest point from the target set for each source point to establish correspondences; then, the alignment step estimates an optimal transformation ... WebThe locally optimized ransac makes no new assumptions about the data, on the contrary – it makes the above-mentioned assumption valid by applying local optimization to the solution estimated from the random sample. The performance of the improved ransac is evaluated in a number of epipolar geometry and homography estimation experiments. greek gift shops in new york
