Class for computing BRIEF descriptors described in calon2010 .

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

static Ptr< BriefDescriptorExtractor > cv::xfeatures2d::BriefDescriptorExtractor::create(
int bytes = 32,
bool use_orientation = false )

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

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.
