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. Most directly related to our approach, several algorithms WebMar 17, 2015 · RANSAC is an iterative method for estimating mathematical model parameters from observed data that contain outliers. RANSAC assumes that when an usually small set of inliers is involved, a procedure that estimates model parameters that optimally explain or fit these data can be applied.
