Bilateral Blur node allows the user to blur images while retaining their sharp edges. Blurring can be controlled by following controls: *Iterations *Color Sigma *Space Sigma Also image input to blur and a determinator image is provided. The node produces a blurred image as its output. The more iterations are provided, the smoother the result. Use color and space sigmas to control the amount of blur. One way to use the determinator input is to feed a mix (add) of Z and normal passes to it. Examples of usage: Ambient Occlusion smoothing - http://wiki.blender.org/index.php/Image:Bilateral_blur_example_01.blend Blurry Refraction - http://wiki.blender.org/index.php/Image:Bilateral_blur_example_02.blend Smoothed shadows and smoothed Ambient Occlusion combined - http://wiki.blender.org/index.php/Image:Bilateral_blur_example_03.blend If you check out the examples, render the image and alter the values to see how they affect. More information about the algorithm can be found at http://homepages.inf.ed.ac.uk/rbf/CVonline/LOCAL_COPIES/MANDUCHI1/Bilateral_Filtering.html . Thanks to Vilem Novak for contributing the patch.
