Detailed Description

Blender which uses multi-band blending algorithm (see [31]).

Constructor & Destructor Documentation

◆ MultiBandBlender()

cv::detail::MultiBandBlender::MultiBandBlender ( int  try_gpu = false,
int  num_bands = 5,
int  weight_type = CV_32F 
)
Python:
<detail_MultiBandBlender object>=cv.detail_MultiBandBlender([, try_gpu[, num_bands[, weight_type]]])

Member Function Documentation

◆ blend()

void cv::detail::MultiBandBlender::blend ( InputOutputArray  dst,
InputOutputArray  dst_mask 
)
virtual
Python:
dst, dst_mask=cv.detail_MultiBandBlender.blend(dst, dst_mask)

Blends and returns the final pano.

Parameters
dstFinal pano
dst_maskFinal pano mask

Reimplemented from cv::detail::Blender.

◆ feed()

void cv::detail::MultiBandBlender::feed ( InputArray  img,
InputArray  mask,
Point  tl 
)
virtual
Python:
None=cv.detail_MultiBandBlender.feed(img, mask, tl)

Processes the image.

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

Reimplemented from cv::detail::Blender.

◆ numBands()

int cv::detail::MultiBandBlender::numBands ( ) const
inline
Python:
retval=cv.detail_MultiBandBlender.numBands()

◆ prepare()

void cv::detail::MultiBandBlender::prepare ( Rect  dst_roi)
virtual
Python:
None=cv.detail_MultiBandBlender.prepare(dst_roi)

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.

◆ setNumBands()

void cv::detail::MultiBandBlender::setNumBands ( int  val)
inline
Python:
None=cv.detail_MultiBandBlender.setNumBands(val)
