points = detectSURFFeatures(I) returns a SURFPoints object, points, containing information about SURF features detected in the 2-D grayscale or binary input image I. The detectSURFFeatures function implements the Speeded-Up Robust Features (SURF) algorithm to find blob features.

Object Recognition using Speeded-Up Robust Features (SURF) is composed of three steps: feature extraction, feature description, and feature matching. This example performs feature extraction, which is the first step of the SURF algorithm.

SURF will detect landmark points in an image, and describe % the points by a vector which is robust against (a little bit) rotation % ,scaling and noise. It can be used in the same way as SIFT (Scale-invariant % feature transform) which is patented.

Strength of detected feature, specified as a numeric value or as an -element vector. The SURF algorithm uses a determinant of approximated Hessian as the metric. Orientation of the detected feature, specified as a numeric scalar or an -element vector. Values must be an angle, in radians.

Mar 19, 2019 · The SURF method (Speeded Up Robust Features) is a fast and robust algorithm for local, similarity invariant representation and comparison of images.

In computer vision, speeded up robust features (SURF) is a local feature detector and descriptor, with patented applications. It can be used for tasks such as object recognition, image registration, classification, or 3D reconstruction.

Match the number of strongest features with each image. Take the ratio of- number of features matched/ number of strongest features (which is 50). If I have two images of the same object (two images taken separately on a camera), ideally the ratio should be near 1 or near 100%.

Matlab implementation of SURF algorithm to detect and match key-points in real time.
