Member Function Documentation

◆ clear()

void cv::quality::QualityBase::clear ( )
inlinevirtual
Python:
cv.quality_QualityBase.clear() -> None

◆ compute()

virtual cv::Scalar cv::quality::QualityBase::compute ( InputArray  img)
pure virtual
Python:
cv.quality_QualityBase.compute(img) -> retval

Compute quality score per channel with the per-channel score in each element of the resulting cv::Scalar. See specific algorithm for interpreting result scores.

Parameters
imgcomparison image, or image to evalute for no-reference quality algorithms

Implemented in cv::quality::QualityPSNR, cv::quality::QualityBRISQUE, cv::quality::QualityGMSD, cv::quality::QualitySSIM, and cv::quality::QualityMSE.

◆ empty()

bool cv::quality::QualityBase::empty ( ) const
inlinevirtual
Python:
cv.quality_QualityBase.empty() -> retval

◆ getQualityMap()

virtual void cv::quality::QualityBase::getQualityMap ( OutputArray  dst) const
inlinevirtual
Python:
cv.quality_QualityBase.getQualityMap([, dst]) -> dst

Returns output quality map that was generated during computation, if supported by the algorithm.
