The SURF is achieved by computing the Hessian matrix with integral images, which reduces the computation cost drastically. In general, the SURF algorithm is composed of three stages: feature point detector, feature point descriptor …
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. WebSURF was first presented at the ECCV 2006 conference in Graz (Austria). Please reference the CVIU journal version: Herbert Bay, Andreas Ess, Tinne Tuytelaars, Luc Van ...
