WebMar 14, 2024 · So the formula for adding Gaussian noise to the image by "imnoise" is given by: output = input + sqrt (v)*randn (size (input)) + mu; %v is the provided variance and mu the mean. Now, in the first line, we are drawing 500*500 random values from a normal distribution with a mean of "mu" and variance "v". The mean and variance of the drawn …
