Using Keypoint Detector and Descriptor Extractor for ROI Transformation with cv2.warpAffine Across Multiple ROIs
I’m using a keypoint detector and descriptor extractor to generate a transformation matrix (M) and then applying it to multiple regions of interest (ROIs) in an image using cv2.warpAffine. However, while applying the transformation to a single ROI works fine (the same ROI used to generate the matrix), applying it to different ROIs fails to produce the expected result.
