SmoothImage_Deriche

Smooths an image using Deriche filter.

Syntax

void avl::SmoothImage_Deriche
(
	const avl::Image& inImage,
	atl::Optional<const avl::Region&> inRoi,
	const atl::real inAlphaX,
	atl::Optional<atl::real> inAlphaY,
	avl::Image& outImage
)

void SmoothImage_Deriche
(
	AvlNet.Image inImage,
	AvlNet.Region inRoi,
	float inAlphaX,
	float? inAlphaY,
	out AvlNet.Image outImage
)

Parameters

Name	Type	Default	Description
inImage	const Image&		Input image
inRoi	Optional<const Region&>	NIL	Range of output pixels to be computed
inAlphaX	const real	1.0f	Horizontal coefficient
inAlphaY	Optional<real>	NIL	Vertical coefficient
outImage	Image&		Output image

Hints

To make smoothing stronger, decrease the inAlphaX and - optionally - inAlphaY.
If the smoothing kernel is not very big, it is recommended to use SmoothImage_Gauss instead.

Examples

SmoothImage_Deriche performed on a sample image with inAlphaX = 0.5.

Hardware Acceleration

This operation supports automatic parallelization for multicore and multiprocessor systems.
