Basic| Module: | OpenCV |
|---|
Perform image denoising using Non-local Means Denoising algorithm.
| Name | Type | Range | Description | |
|---|---|---|---|---|
 |
inImages | ImageArray | ||
|
inFilterStrength | RealArray | Parameter regulating filter strength for luminance component. Bigger h value perfectly removes noise but also removes image details, smaller h value preserves details but also preserves some noise. | |
|
inImageIndex | Integer | 0 -  |
Target image to denoise index. |
|
inTemporalWindowSize | Integer | 1 - |
Number of surrounding images to use for target image denoising. Should be odd. |
|
inTemplateWindowSize | Integer | 1 - |
Size in pixels of the template patch that is used to compute weights. Should be odd. |
|
inSearchWindowSize | Integer | 1 - |
Size in pixels of the window that is used to compute weighted average for given pixel. Should be odd. Affect performance linearly. |
