MATLAB: Mu and sigma for every pixel evfitmusigma how to calculate mu and sigma for every pixel of a frame of a video or help me in using evfit for this situation Best Answer mu is the pixel value. sigma is zero.mu = mean(rgbImage(row, column, colorChannel)); % Same as the pixel value.sigma = std(rgbImage(row, column, colorChannel)); % This will be zero since it's just one value.I never heard of evfit.
