Module noise

Functions for adding synthetic noise to images.

Functions

• gaussian_noise
  Adds independent additive Gaussian noise to all channels of an image, with the given mean and standard deviation.
• gaussian_noise_mut
  Adds independent additive Gaussian noise to all channels of an image in place, with the given mean and standard deviation.
• salt_and_pepper_noise
  Converts pixels to black or white at the given rate (between 0.0 and 1.0). Black and white occur with equal probability.
• salt_and_pepper_noise_mut
  Converts pixels to black or white in place at the given rate (between 0.0 and 1.0). Black and white occur with equal probability.
