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:

◆ 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
