Member Function Documentation

blend()

void cv::detail::FeatherBlender::blend ( InputOutputArray  dst, InputOutputArray  dst_mask  )

virtual

Blends and returns the final pano.

Parameters

dst	Final pano
dst_mask	Final pano mask

Reimplemented from cv::detail::Blender.

createDefault()

static Ptr<Blender> cv::detail::Blender::createDefault ( int  type, bool  try_gpu = false  )

staticinherited

createWeightMaps()

Rect cv::detail::FeatherBlender::createWeightMaps	(	const std::vector< UMat > &	masks,
		const std::vector< Point > &	corners,
		std::vector< UMat > &	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

Processes the image.

Parameters

img	Source image
mask	Source image mask
tl	Source image top-left corners

Reimplemented from cv::detail::Blender.

prepare() [1/2]

virtual void cv::detail::Blender::prepare ( const std::vector< Point > &  corners, const std::vector< Size > &  sizes  )

virtualinherited

Prepares the blender for blending.

Parameters

corners	Source images top-left corners
sizes	Source image sizes

prepare() [2/2]

void cv::detail::FeatherBlender::prepare ( Rect  dst_roi )

virtual

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

Examples:

samples/cpp/stitching_detailed.cpp.
