An automatic approach to lossy compression of images corrupted by Poisson noise

Lossy compression of images corrupted by Poisson noise is considered. Peculiarities on noisy images are discussed. An automatic approach in selection of a parameter that controls compression ratio (CR) is proposed. It is demonstrated how to reach optimal operation point (OOP), i.e., such CR that pro...

Description
Summary:Lossy compression of images corrupted by Poisson noise is considered. Peculiarities on noisy images are discussed. An automatic approach in selection of a parameter that controls compression ratio (CR) is proposed. It is demonstrated how to reach optimal operation point (OOP), i.e., such CR that provides minimal peak signal-to noise ratio (PSNR) calculated between compressed and noise free images without having an actual noise-free image. A provided CR is of about 6...16 and it depends upon image complexity.
