Webb1. RANSAC algorithm Random sample consensus (RANSAC) was originally presented in the seminal work [ FB81] and is still widely used nowadays (e.g. in the front-end of Visual SLAM or Visual Odometry systems). For a theoretical description of the algorithm, refer to [ FB81] or to this Wikipedia article and the cites herein.
