Optimal randomized ransac

WebThis bound polynomially improves all existing bounds for algorithms based on randomized value functions, and for the first time, matches the Ω(H √SAT) Ω ( H S A T) lower bound up to logarithmic factors. Our result highlights that randomized exploration can be near-optimal, which was previously achieved only by optimistic algorithms. WebApr 11, 2024 · It has been observed that, to find an optimal solution (with a given probability), the number of samples drawn in ransac is significantly higher than predicted from the mathematical model.

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.
