addNoiseToImage

Description

Add noise to image using additive Guassian, salt-and-pepper, shot, or speckle noise.

Usage

addNoiseToImage(
  image,
  noiseModel = c("additivegaussian", "saltandpepper", "shot", "speckle"),
  noiseParameters
)

Arguments

image	input image
noiseModel	either "additivegaussian", "saltandpepper", "shot", or "speckle".
noiseParameters	vector defining the noise models. additivegaussian: (mean, standardDeviation), saltandpepper: (probability, saltValue, pepperValue), shot: (scale), speckle: (standardDeviation),

Value

noise corrupted image.
