In physical process, Poisson noise usually is added first, before Gaussian noise.
It needs to draw attention, noise reduction approaches that have been developed based on wavelet transform are only for Gaussian or Poisson noise.
Poisson Noise is a multiplicative noise having an uncertain nature which is associated with the estimation of light.
Different levels of Gaussian white noise ([sigma] =50 and 250), Poisson noise ([sigma] =50 and 250) and mixture of both ([sigma] = 50,a = 50 and [sigma] = 250, [sigma] = 250) are added to the original image.
Furthermore, we consider f instead of g, with f being corrupted by Poisson noise.
