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
