詳解

Class for implementing the wrapper which makes detectors and extractors to be affine invariant, described as ASIFT in [YM11] .

関数詳解

◆ create()

static CV_WRAP Ptr< AffineFeature > cv::AffineFeature::create	(	const Ptr< Feature2D > &	backend,
		int	maxTilt = `5`,
		int	minTilt = `0`,
		float	tiltStep = `1.4142135623730951f`,
		float	rotateStepBase = `72`
	)

static

引数

backend	The detector/extractor you want to use as backend.
maxTilt	The highest power index of tilt factor. 5 is used in the paper as tilt sampling range n.
minTilt	The lowest power index of tilt factor. 0 is used in the paper.
tiltStep	Tilt sampling step $\delta_t$ in Algorithm 1 in the paper.
rotateStepBase	Rotation sampling step factor b in Algorithm 1 in the paper.

◆ getDefaultName()

virtual CV_WRAP String cv::AffineFeature::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.
