A denoising scheme for astronomical color images/videos corrupted with Poisson noise is proposed.
The above denoising methodology is extended for Poisson noise corrupted astronomical videos by taking spatial correlation into account.
Performance Comparison of Various Filters for Removing Gaussian and Poisson Noises

This is the known modified ROF model to remove Poisson noise.
We consider, the noise variance is unchangeable (Poisson noise is not changed and Gaussian noise only depends on noise variance):
is a multiplicative noise having an uncertain nature which is associated with the estimation of light.
TV Numerical Algorithms for the Poisson Noise
The noise in the sinogram is a priori identified as a Poisson noise
Compressive sensing with Poisson noise
. For the validation of the error estimates in the Poisson case we consider the following discrete inverse problem.
Thus the false patterns created by the Poisson noise
are adequately smoothed out by all the disease-mapping models.
Different levels of Gaussian noise, Poisson noise
, or mixture of both are added to the images in the public testing dataset .
Both moments are very robust to the salt and pepper noise and poisson noise
. TM also has the same properties with KM and KMI; however, when the salt and pepper noise has a ratio of 20%, its recognition rate is just 0.9.
