Several kind of noise can be found in real images, mostly depending on the modality of acquisition. It is often useful to be able to simulate that noise, for example to test the behavior of an algorithm in the presence of a known amount of noise. This contribution provides the filters to generate four kind of noise -- additive gaussian, shot, speckle and salt and pepper -- as well as a PSNR calculator.
