Member Function Documentation

◆ blend()

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

Blends and returns the final pano.

Parameters
dstFinal pano
dst_maskFinal pano mask

Reimplemented in cv::detail::FeatherBlender, and cv::detail::MultiBandBlender.

◆ createDefault()

static Ptr< Blender > cv::detail::Blender::createDefault ( int type,
bool try_gpu = false )
static
Python:
cv.detail.Blender.createDefault(type[, try_gpu]) -> retval
cv.detail.Blender_createDefault(type[, try_gpu]) -> retval

◆ feed()

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

Processes the image.

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

Reimplemented in cv::detail::FeatherBlender, and cv::detail::MultiBandBlender.

◆ prepare() [1/2]

virtual void cv::detail::Blender::prepare ( const std::vector< Point > & corners,
const std::vector< Size > & sizes )
virtual
Python:
cv.detail.Blender.prepare(corners, sizes) -> None
cv.detail.Blender.prepare(dst_roi) -> None

Prepares the blender for blending.

Parameters
cornersSource images top-left corners
sizesSource image sizes

◆ prepare() [2/2]

virtual void cv::detail::Blender::prepare ( Rect dst_roi)
virtual
Python:
cv.detail.Blender.prepare(corners, sizes) -> None
cv.detail.Blender.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 in cv::detail::FeatherBlender, and cv::detail::MultiBandBlender.
