In this chapter, we have covered a widely used OpenCV component. Local features are a key part of relevant computer vision algorithms such as object recognition, object tracking, image stitching, and camera calibration. An introduction and several samples have been provided, thus covering interest points detection using different algorithms, extraction of descriptors from interest points, matching descriptors, and filtering the results.
