Perform image denoising using Non-local Means Denoising algorithm.
| Name | Type | Range | Description | |
|---|---|---|---|---|

inImage | Image | Input image | |
|
inFilterStrength | RealArray | Parameter regulating filter strength. Big h value perfectly removes noise but also removes image details, smaller h value preserves details but also preserves some noise. | |
|
inTemplateWindowSize | Integer | 1 -  |
Size in pixels of the window that is used to compute weighted average for given pixel. Should be odd. Affect performance linearly. |
|
inSearchWindowSize | Integer | 1 - |
Size in pixels of the template patch that is used to compute weights. Should be odd. |
