詳解

Class implements both functionalities for detection of lines and computation of their binary descriptor.

Class' interface is mainly based on the ones of classical detectors and extractors, such as Feature2d's Feature Detection and Description and Descriptor Matchers. Retrieved information about lines is stored in line_descriptor::KeyLine objects.
