An improved ORB feature extraction and matching algorithm based on affine transformation

As the key technology of image processing, image feature extraction and matching are widely used in face recognition, image stitching, and visual SLAM. Among them, ORB algorithm is widely adopted because of its advantage in real-time processing. However, the matching accuracy of the feature points extracted by ORB algorithm is still a concern for further applications. To address the problem, an improved ORB algorithm based on affine...
