- @C1@c@b@_ Smooth
-
- To smooth an image or a part of it using a special convolution
- kernel in which each pixel is influenced by its neighbors
-
- @b Interaction
-
- @b Smoothing Region
- Smooth region is defined by a rubber band whose size and location can
- be manipulated interactively by clicking on the small crosses on the
- rubber band. Keyboard arrow keys (or ijkl) can also be used.
- If control key is down, all commands move the rubber band rigidly.
-
- @b Smoothing method
- Currently only 3x3 and 5x5 kernels are supported with 3x3 having
- a less strength than 5x5.
-
- @b Threshold
- To preserve edge, a threshold may be used. The threshold is used
- as follows:
-
- if (abs(SmoothedPixel - OldPixel) >= Threshold)
- NewPixel = SmoothedPixel
- else
- NewPixel =OldPixel
- Thresold can be set for RGB separately
-
- @ Other controls
- Click on Undo to undo all smoothes since last Save.
- Click on Smooth to initiating smooth.
- Click on Done to finish
-
- @b Note
- Resulting image is in RGB regardless of the input image type.
