Extractors 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 computing descriptors
represented as vectors in a multidimensional space. All objects that implement the vector
descriptor extractors inherit the
DescriptorExtractor
interface.
