Optimal randomized ransac

WebRandom sample consensus (RANSAC) algorithm, which has been widely used in feature extraction in computer vision, is introduced in this paper to achieve higher prediction … 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.

WebThe Random Sample Consensus (RANSAC) algorithm is a popular tool for robust estimation problems in computer vision, primarily due to its ability to tolerate a tremendous fraction of outliers. There have been a number of recent efforts that aim to increase the efficiency of the standard RANSAC algorithm. Websame paper, leading to an optimal randomized RANSAC formulation. MLESAC [24] takes a different approach by improving the rating function for models. Instead of count-ing inliers to a model, it uses the maximum likelihood esti-mate as score to directly rate estimation quality.
