Non-Local Euclidean Medians

Non-local patch-based image denoising using Non-Local Euclidean Medians (NLEM).

File Information

MATLAB implementation of the Non-Local Euclidean Medians (NLEM) algorithm described in the following paper:

[1] K.N. Chaudhury, and M. Unser, "Non-Local Euclidean Medians", IEEE Signal
Processing Letters, vol. 19, no. 11, 2012.

The current implementation is meant for experimental usage, and is far from optimal in terms of efficiency. For example, it can be optimized using *parfor* loops, or using mex code for computing the Euclidean median.

Worked better than non-local mean on my dataset but took much longer time. It would be great if providing a faster version. Tried parfor, but got alerts due to variables are sliced within the for loops. Any idea to dramatically improve the speed? Thanks!

Royi Avital: NLEM does better than the classic NLM on images that have lot of sharp intensity jumps. Taking the Euclidean median (instead of the mean) gives better robustness for such images.

Is it any better than the classic NLM?

nice.but what about NLEM version for color image ?
