virtual void cv::ximgproc::EdgeAwareInterpolator::setCostMap ( const Mat &  _costMap )

Parameter to tune the approximate size of the superpixel used for oversegmentation.

See also

cv::ximgproc::createSuperpixelSLIC

K is a number of nearest-neighbor matches considered, when fitting a locally affine model. Usually it should be around 128. However, lower values would make the interpolation noticeably faster.

setLambda()

virtual void cv::ximgproc::EdgeAwareInterpolator::setLambda ( float  _lambda )

pure virtual

Python:
	cv.ximgproc.EdgeAwareInterpolator.setLambda(	_lambda	) ->	None

Lambda is a parameter defining the weight of the edge-aware term in geodesic distance, should be in the range of 0 to 1000.

setSigma()

virtual void cv::ximgproc::EdgeAwareInterpolator::setSigma ( float  _sigma )

pure virtual

Python:
	cv.ximgproc.EdgeAwareInterpolator.setSigma(	_sigma	) ->	None

Sigma is a parameter defining how fast the weights decrease in the locally-weighted affine fitting. Higher values can help preserve fine details, lower values can help to get rid of noise in the output flow.

setUsePostProcessing()

pure virtual

Python:
	cv.ximgproc.EdgeAwareInterpolator.setUsePostProcessing(	_use_post_proc	) ->	None
