Member Function Documentation

create()

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

static

Python:
	cv.xfeatures2d.BriefDescriptorExtractor.create(	[, bytes[, use_orientation]]	) ->	retval
	cv.xfeatures2d.BriefDescriptorExtractor_create(	[, bytes[, use_orientation]]	) ->	retval

getDefaultName()

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

virtual

Python:
	cv.xfeatures2d.BriefDescriptorExtractor.getDefaultName(		) ->	retval

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.

getDescriptorSize()

virtual int cv::xfeatures2d::BriefDescriptorExtractor::getDescriptorSize ( ) const

pure virtual

Python:
	cv.xfeatures2d.BriefDescriptorExtractor.getDescriptorSize(		) ->	retval

getUseOrientation()

virtual bool cv::xfeatures2d::BriefDescriptorExtractor::getUseOrientation ( ) const

pure virtual

Python:
	cv.xfeatures2d.BriefDescriptorExtractor.getUseOrientation(		) ->	retval

setDescriptorSize()

virtual void cv::xfeatures2d::BriefDescriptorExtractor::setDescriptorSize ( int bytes )

pure virtual

Python:
	cv.xfeatures2d.BriefDescriptorExtractor.setDescriptorSize(	bytes	) ->	None

setUseOrientation()

virtual void cv::xfeatures2d::BriefDescriptorExtractor::setUseOrientation ( bool use_orientation )

pure virtual

Python:
	cv.xfeatures2d.BriefDescriptorExtractor.setUseOrientation(	use_orientation	) ->	None
