Advanced| Module: | FoundationLite |
|---|
Smooths an image using Deriche filter.
Applications
Approximation of the gaussian filter, which can be faster for large kernels.
| Name | Type | Range | Description | |
|---|---|---|---|---|
 |
inImage | Image | Input image | |
|
inRoi | Region* | Range of output pixels to be computed | |
|
inAlphaX | Real | 0.001 -  |
Horizontal coefficient |
|
inAlphaY | Real* | 0.001 - |
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.

List of possible exceptions:
| Error type | Description |
|---|---|
| DomainError | Region exceeds an input image in SmoothImage_Deriche. |
Complexity Level
This filter is available on Advanced Complexity Level.
Filter Group
This filter is member of SmoothImage filter group.
