In computer vision, speeded up robust features (SURF) is a patented local feature detector and descriptor. It can be used for tasks such as object recognition, image registration, classification, or 3D reconstruction. It is partly inspired by the scale-invariant feature transform (SIFT) descriptor. The standard version of SURF is several times faster than SIFT and claimed by its authors to be more robust against different image transformations than SIFT. WebAug 8, 2024 · Speed up Robust Features (SURF) algorithm is an effective feature point extraction algorithm and its high efficiency and high stability are superior to similar …
