Abstract
We propose a new measure for denoising image by calculating mean distance of all pixels in an image in
non-local means (NL-means) algorithm.
We compute and analyze the original NL-means algorithm which
total all the distance of the patches but, our proposed algorithm calculates the mean value of all distance of
all the patches and then than get the sum of all distance.
Our proposed algorithm exhibit better result with
comparison of
Less
