cv2.findHomography is an OpenCV function that computes a 3x3 homography matrix from a set of corresponding points between two planes. Given source and destination point coordinates and a robust estimation method such as RANSAC or LMEDS, it returns a matrix with incorrect matches filtered out along with an inlier mask. It is used for image registration, panorama stitching, and planar object tracking.
