SharpenShock node¶
This documentation is for version 2.0 of SharpenShock (net.sf.cimg.CImgSharpenShock).
Description¶
Sharpen selected images by shock filters.
Uses ‘sharpen’ function from the CImg library.
CImg is a free, open-source library distributed under the CeCILL-C (close to the GNU LGPL) or CeCILL (compatible with the GNU GPL) licenses. It can be used in commercial applications (see http://cimg.eu).
Inputs¶
| Input | Description | Optional |
|---|---|---|
| Source | No | |
| Mask | Yes |
Controls¶
| Parameter / script name | Type | Default | Function |
|---|---|---|---|
Amplitude / amplitude |
Double | 0.6 | Standard deviation of the spatial kernel, in pixel units (>=0). Details smaller than this size are filtered out. |
Edge Threshold / edgeThreshold |
Double | 0.1 | Edge threshold. |
Gradient Smoothness / alpha |
Double | 0.8 | Gradient smoothness (in pixels). |
Tensor Smoothness / sigma |
Double | 1.1 | Tensor smoothness (in pixels). |
Iterations / iterations |
Integer | 1 | Number of iterations. A reasonable value is 1. |
(Un)premult / premult |
Boolean | Off | Divide the image by the alpha channel before processing, and re-multiply it afterwards. Use if the input images are premultiplied. |
Invert Mask / maskInvert |
Boolean | Off | When checked, the effect is fully applied where the mask is 0. |
Mix / mix |
Double | 1 | Mix factor between the original and the transformed image. |
