SmoothImage_Deriche
Smooths an image using Deriche filter.
Header: | AVL.h |

Syntax
C++
C#
void avl::SmoothImage_Deriche ( const avl::Image& inImage, atl::Optional<const avl::Region&> inRoi, const float inAlphaX, atl::Optional<float> inAlphaY, avl::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 float | 1.0f | Horizontal coefficient |
![]() |
inAlphaY | Optional<float> | 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.
