Digikam SoK 2012 Auto Noise Reduction

DigiKam already has a good noise reduction algorithm but it is with manual NR settings. What we need is a Automatic NR settings adjustment option depending upon the input image's noise level and the type of noise present. This would automate the task and will also make it easier for newbies to find the NR settings which 'just works' for the input image.

One of the primary goal is to implement a Noise Level Function (NFL) which works using using a single image[1]. Secondly we need to map the obtained Noise Level to the already present NR settings (This would certainly require much of testing with the real image dataset). Here is the Bugzilla entry
