As an example, if you use the following image:
Parameter | Value |
Radius | 6 |
Opacity | 100 |
The following figure results:
If the image has a region, the command will be applied on the region only.
For more information, refer to Removing Noise.
Run the HighPassCommand on an image and applies the HighPass filter.
