Parameters
- src
- Type: OpenCvSharpInputArray
Input 8-bit 3-channel image. - dst
- Type: OpenCvSharpOutputArray
Output image with the same size and type as src. - h (Optional)
- Type: SystemSingle
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 - hColor (Optional)
- Type: SystemSingle
The same as h but for color components. For most images value equals 10 will be enought
to remove colored noise and do not distort colors - templateWindowSize (Optional)
- Type: SystemInt32
Size in pixels of the template patch that is used to compute weights. Should be odd. Recommended value 7 pixels - searchWindowSize (Optional)
- Type: SystemInt32
Size in pixels of the window that is used to compute weighted average for given pixel. Should be odd.
Affect performance linearly: greater searchWindowsSize - greater denoising time. Recommended value 21 pixels
