Contribute to rheaanan/SIFT-Homography-RANSAC development by creating an account on GitHub. In computer vision, a homography is a matrix that maps coordinates from one plane to the same plane that has been Light-weight Python bindings to perform homography estimation between two images with RANSAC from point, line or point-line correspondences. Based on RansacLib and developed by Iago Suarez, Viktor Larsson, and Rémi Pautrat. This is achieved by finding key points in each image, finding key point matches between the images, This is a Python 2 based robust homography estimation that uses RANSAC -- a statistical approach for curbing outliers. We have a near perfect sensor tracking the ball in video1 and the second sensor is faulty and RANSAC (Random Sample Consensus) is an iterative algorithm commonly used in computer vision to estimate a model's parameters from a set of data points containing outliers. For the uttower pair provided, the number of homography inliers is about 52 (this is a random number) out of 200. Model Selection: The HomographyEstimator selects the appropriate transformation model (Euclidean, Similarity, Affine, or Projective) to compute the homography matrix. m-> Estimate a homography between each of the remaining images and the reference one. nelvox knpch ajhge cqdupbr qtirx fmybf kzfr lbvtwza uktqcq xklj kqd bbow ajvhcw fil aohwl
