The Random Sample Consensus (RANSAC) algorithm was introduced by Fischler and Bolles in 1981. The motivation for developing this algorithm came from the field of computer vision, where they were working on the problem of interpreting and recognizing three-dimensional scenes from two-dimensional image data. The traditional least-squares method for f...
Random Sample Consensus (RANSAC) is an iterative method for robustly fitting a model to data. Its key strength is the ability to handle large amounts of outliers, making it suitable for applications in fields like computer vision, robotics, and geosciences. RANSAC operates on the assumption that, within a dataset, there exist "inliers", data that c...
