Member Function Documentation

blend()

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

virtual

Python:
	dst, dst_mask	=	cv.detail_FeatherBlender.blend(	dst, dst_mask	)

Blends and returns the final pano.

Parameters

dst	Final pano
dst_mask	Final 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:
	retval, weight_maps	=	cv.detail_FeatherBlender.createWeightMaps(	masks, corners, 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:
	None	=	cv.detail_FeatherBlender.feed(	img, mask, tl	)

Processes the image.

Parameters

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

Reimplemented from cv::detail::Blender.

prepare()

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

virtual

Python:
	None	=	cv.detail_FeatherBlender.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.

setSharpness()

void cv::detail::FeatherBlender::setSharpness ( float  val )

inline

Python:
	None	=	cv.detail_FeatherBlender.setSharpness(	val	)

Examples:

samples/cpp/stitching_detailed.cpp.

sharpness()

float cv::detail::FeatherBlender::sharpness ( ) const

inline

Python:
	retval	=	cv.detail_FeatherBlender.sharpness(		)

Examples:

samples/cpp/stitching_detailed.cpp.
