cv.DescriptorMatcher

Common interface for matching keypoint descriptors.

Class for matching keypoint descriptors.

Matchers of keypoint descriptors in OpenCV have wrappers with a common interface that enables you to easily switch between different algorithms solving the same problem. This section is devoted to matching descriptors that are represented as vectors in a multidimensional space. All objects that implement vector descriptor matchers inherit the DescriptorMatcher interface.

It has two groups of match methods: for matching descriptors of an image with another image or with an image set.

Example

X = rand(100,10);
Y = rand(100,10);
matcher = cv.DescriptorMatcher('BruteForce');
matcher.add(X);
matcher.train();  % Optional for BruteForce matcher
matches = matcher.match(Y);
