Noise Level Estimation
This implementation estimate noise level in an image as specified in paper
entitled as Single-Image Noise Level Estimation for Blind Denoising by
Xinhao Liu, Masayuki Tanaka, and Masatoshi Okutomi.
Function NLEstimate is the main file which perform this task. Detail are as,
INPUTS:
I = Image
ps = Patch Size (Optional); default size in 7
maxiter = Number of iteration (Optional); default value is 5
OUTPUTS:
ENL = Estimated Noise Level Can be a single value if I is
grayscale image or vector of 1 X 3 dimension if I is
RGB image representing in red, green and blue channel
USAGE:
Estimate Noise Level with default value.
ENL = NLEstimate(imread('football.jpg')); % Return Estimated noise level
for all channel in an image, i.e. for red, green, and blue
ENL = NLEstimate(rgb2gray(imread('football.jpg'))); % Return Estimated
noise level.
