Color estimation under Poisson noise
H.J. Trussell, Michael J. Vrhel · 2013
The dominance of Poisson noise over signal independent Gaussian noise and other types has been demonstrated for commercial digital color cameras. We present a new method for estimating CIE colorimeric values in the presence of Poisson noise. The new methods use multidimensional look-up tables (MLUTs) and are easily adapted to the local statistics of the image. The methods are shown to perform better than common methods that are based on signal independent noise models.
