TīmeklisAs an alternative to throwing out outliers, we will look at a robust method of regression using the RANdom SAmple Consensus (RANSAC) algorithm, which fits a regression … TīmeklisRANSAC. Random sample consensus is an iterative method for estimation of parameters of a mathematical model. We will model the transformation of points in source image to destination one, and try to find an estimate of model parameters. The basic idea of RANSAC algorithm is shown in the following flow chart. RANSAC is a … TīmeklisWhile ransac.Ransac always fits a single model, ransac.XRansac or ransac.JLinkage can be used to detect and fit multiple underlying models. The number of models does not need to be specified in advance. XRansac is faster but uses additional parameters. See this IPython notebook for more complete examples.
