It's just not good enough and I don't really know what may left to do. Workflow: - Loading images - Detecting features with ORB - Extracting features with ORB - Matching with BruteForce (Hamming-(2)) - Ratio test - Symmetry test - Calculating Homography using RANSAC - Warping But still, my matches (without RANSAC) look like that: [Matched Features](/upfiles/14522078701034283.jpg)
