Constructor & Destructor Documentation

◆ GainCompensator() [1/2]

cv::detail::GainCompensator::GainCompensator ( )
inline
Python:
cv.detail.GainCompensator() -> <detail_GainCompensator object>
cv.detail.GainCompensator(nr_feeds) -> <detail_GainCompensator object>

◆ GainCompensator() [2/2]

cv::detail::GainCompensator::GainCompensator ( int nr_feeds)
inline
Python:

cv.detail.GainCompensator(nr_feeds) -> <detail_GainCompensator object>

Member Function Documentation

◆ apply()

void cv::detail::GainCompensator::apply ( int index,
Point corner,
InputOutputArray image,
InputArray mask )
virtual
Python:
cv.detail.GainCompensator.apply(index, corner, image, mask) -> image

Compensate exposure in the specified image.

Parameters
indexImage index
cornerImage top-left corner
imageImage to process
maskImage mask

Implements cv::detail::ExposureCompensator.

◆ feed()

void cv::detail::GainCompensator::feed ( const std::vector< Point > & corners,
const std::vector< UMat > & images,
const std::vector< std::pair< UMat, uchar > > & masks )
virtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Implements cv::detail::ExposureCompensator.

◆ gains()

std::vector< double > cv::detail::GainCompensator::gains ( ) const

◆ getMatGains()

void cv::detail::GainCompensator::getMatGains ( std::vector< Mat > & umv)
virtual
Python:
cv.detail.GainCompensator.getMatGains([, umv]) -> umv

Reimplemented from cv::detail::ExposureCompensator.

◆ getNrFeeds()

int cv::detail::GainCompensator::getNrFeeds ( )
inline
Python:
cv.detail.GainCompensator.getNrFeeds() -> retval

◆ getSimilarityThreshold()

double cv::detail::GainCompensator::getSimilarityThreshold ( ) const
inline
Python:
cv.detail.GainCompensator.getSimilarityThreshold() -> retval

◆ prepareSimilarityMask()

void cv::detail::GainCompensator::prepareSimilarityMask ( const std::vector< Point > & corners,
const std::vector< UMat > & images )

◆ setMatGains()

void cv::detail::GainCompensator::setMatGains ( std::vector< Mat > & umv)
virtual
Python:
cv.detail.GainCompensator.setMatGains(umv) -> None

Reimplemented from cv::detail::ExposureCompensator.

◆ setNrFeeds()

void cv::detail::GainCompensator::setNrFeeds ( int nr_feeds)
inline
Python:
cv.detail.GainCompensator.setNrFeeds(nr_feeds) -> None

◆ setSimilarityThreshold()

void cv::detail::GainCompensator::setSimilarityThreshold ( double similarity_threshold)
inline
Python:
cv.detail.GainCompensator.setSimilarityThreshold(similarity_threshold) -> None

◆ singleFeed()

void cv::detail::GainCompensator::singleFeed ( const std::vector< Point > & corners,
const std::vector< UMat > & images,
const std::vector< std::pair< UMat, uchar > > & masks )
