Member Function Documentation

§ blend()

virtual void cv::detail::Blender::blend ( InputOutputArray  dst,
InputOutputArray  dst_mask 
)
virtual
Python:
dst, dst_mask=cv.detail_Blender.blend(dst, dst_mask)

Blends and returns the final pano.

Parameters
dstFinal pano
dst_maskFinal pano mask

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

§ createDefault()

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

§ feed()

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

Processes the image.

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

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

§ prepare() [1/2]

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

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:
None=cv.detail_Blender.prepare(corners, sizes)
None=cv.detail_Blender.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 in cv::detail::MultiBandBlender, and cv::detail::FeatherBlender.
