Detailed Description

Class for computing BRIEF descriptors described in [calon2010] .

Parameters

bytes	legth of the descriptor in bytes, valid values are: 16, 32 (default) or 64 .
use_orientation	sample patterns using keypoints orientation, disabled by default.

static

getDefaultName()

String cv::xfeatures2d::BriefDescriptorExtractor::getDefaultName ( ) const

virtual

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.

Reimplemented from cv::Feature2D.
