I.To generate Gaussian noise Box-Muller:if random variable x and y are respectively independent generated from a uniform distribution with [0,1].we can use the formula below to produce a variable with Gaussian distribution. z=sqrt(-2*lny)*cos(2*pi*x) function: double generateGaussianNoise(...

Hello everyone, How can we add white Gaussian noise to an image with zero mean and standard deviation of 64 gray levels? I do know how to add noise of zero mean and variance using imnoise but I do not know about standard deviation of 64 g...
% snr is the signal-to-noise ratio expressed in decibels % stdev =... z = stdev*randn(size(x)); y = x + z; end 2 Comments minaon 7 Apr 2012 thanks for your help. but this is what i need to do exactly:- implement a MATLAB function to add Gaussian noise to the image ...
Information: Chainner version: Alpha 0.24.1 Description When you want to add camera sensor noise to an image, you need fine control over Monochromatic Gaussian noise. ChaiNNer's Add Noise node is extremely heavy-handed. Even at the lowes...
