Member Function Documentation

◆ blend()

void cv::detail::FeatherBlender::blend ( InputOutputArray dst,
InputOutputArray dst_mask )
virtual
Python:
cv.detail.FeatherBlender.blend(dst, dst_mask) -> dst, dst_mask

Blends and returns the final pano.

Parameters
dstFinal pano
dst_maskFinal pano mask

Reimplemented from cv::detail::Blender.

◆ createWeightMaps()

Rect cv::detail::FeatherBlender::createWeightMaps ( const std::vector< UMat > & masks,
const std::vector< Point > & corners,
std::vector< UMat > & weight_maps )
Python:
cv.detail.FeatherBlender.createWeightMaps(masks, corners, weight_maps) -> retval, weight_maps

Creates weight maps for fixed set of source images by their masks and top-left corners. Final image can be obtained by simple weighting of the source images.

◆ feed()

void cv::detail::FeatherBlender::feed ( InputArray img,
InputArray mask,
Point tl )
virtual
Python:
cv.detail.FeatherBlender.feed(img, mask, tl) -> None

Processes the image.

Parameters
imgSource image
maskSource image mask
tlSource image top-left corners

Reimplemented from cv::detail::Blender.

◆ prepare()

void cv::detail::FeatherBlender::prepare ( Rect dst_roi)
virtual
Python:
cv.detail.FeatherBlender.prepare(dst_roi) -> None

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

Reimplemented from cv::detail::Blender.

◆ setSharpness()

void cv::detail::FeatherBlender::setSharpness ( float val)
inline
Python:
cv.detail.FeatherBlender.setSharpness(val) -> None

◆ sharpness()

float cv::detail::FeatherBlender::sharpness ( ) const
inline
Python:
cv.detail.FeatherBlender.sharpness() -> retval
