inlineprotected

Member Function Documentation

clear()

void cv::quality::QualityGMSD::clear ( )

inlinevirtual

Python:
	cv.quality.QualityGMSD.clear(		) ->	None

Implements Algorithm::clear().

Reimplemented from cv::quality::QualityBase.

compute() [1/2]

cv::Scalar cv::quality::QualityGMSD::compute ( InputArray cmp )

virtual

Python:
	cv.quality.QualityGMSD.compute(	cmp	) ->	retval
	cv.quality.QualityGMSD.compute(	ref, cmp[, qualityMap]	) ->	retval, qualityMap
	cv.quality.QualityGMSD_compute(	ref, cmp[, qualityMap]	) ->	retval, qualityMap

Compute GMSD.

Parameters

cmp	comparison image

Returns

cv::Scalar with per-channel quality value. Values range from 0 (worst) to 1 (best)

Implements cv::quality::QualityBase.

compute() [2/2]

cv::Scalar cv::quality::QualityGMSD::compute ( InputArray ref, InputArray cmp, OutputArray qualityMap )

static

Python:
	cv.quality.QualityGMSD.compute(	cmp	) ->	retval
	cv.quality.QualityGMSD.compute(	ref, cmp[, qualityMap]	) ->	retval, qualityMap
	cv.quality.QualityGMSD_compute(	ref, cmp[, qualityMap]	) ->	retval, qualityMap

static method for computing quality

Parameters

ref	reference image
cmp	comparison image
qualityMap	output quality map, or cv::noArray()

Returns

cv::Scalar with per-channel quality value. Values range from 0 (worst) to 1 (best)

create()

static

Python:
	cv.quality.QualityGMSD.create(	ref	) ->	retval
	cv.quality.QualityGMSD_create(	ref	) ->	retval

Create an object which calculates image quality.

Parameters

ref	reference image

empty()

bool cv::quality::QualityGMSD::empty ( ) const

inlinevirtual

Python:
	cv.quality.QualityGMSD.empty(		) ->	retval

Implements Algorithm::empty().
