WebStep 1: Detect the keypoints and extract descriptors using SURF Step 2: Matching descriptor vectors using FLANN matcher Step 3: Compute homography Step 4: Localize the object Show results WebThat's what RANSAC does for you: it computes a homography and gives you a prediction for which pairs are inliers and which are outliers. In SIFT, we first generate keypoints and the feature vector for each keypoint.
