Fast nlmeans filter
Implementation of the non-local mean filter, using a fast implementation scheme. This implementation is an adaptation of the nl means filter in python scikit skimage module. It is however faster due to OTB streaming and threading strategies.
This filter is used inside the RABASAR filtering algorithm to denoise temporal stack of SAR images. It is however useful for a broader class of images.
Classes and files
Two new files implementing the filter have been added to the Filtering module, inside Smoothing directory :
An application to launch NL Means filter have been added in AppFiltering :
Two tests have been added : one calling the application, the other one testing the filter
