.. _net.sf.cimg.CImgBilateral: SmoothBilateral node ==================== .. raw:: html |pluginIcon|  *This documentation is for version 2.0 of SmoothBilateral (net.sf.cimg.CImgBilateral).* Description ----------- Blur input stream by bilateral filtering. Uses the ‘blur_bilateral’ function from the CImg library. See also: http://opticalenquiry.com/nuke/index.php?title=Bilateral 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).

A reasonable value is 1/16 of the image dimension. Small values (1 pixel and below) will slow down filtering. | +-------------------------------+---------+---------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Value Std Dev / ``sigma_r`` | Double | 0.3 | Standard deviation of the range kernel (color sigma), in intensity units (>=0). A reasonable value is 1/10 of the intensity range. In the context of denoising, Liu et al. (“Noise estimation from a single image”, CVPR2006) recommend a value of 1.95*sigma_n, where sigma_n is the local image noise. Small values (1/256 of the intensity range and below) will slow down filtering. | +-------------------------------+---------+---------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Iterations / ``iterations`` | Integer | 2 | Number of iterations. | +-------------------------------+---------+---------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | (Un)premult / ``premult`` | Boolean | Off | Divide the image by the alpha channel before processing, and re-multiply it afterwards.
