Influence of the Lossy Compression JPEG2000 standard on the Deformation of PSF
Original language description
This paper deals with the influence of lossy compression algorithms on the deformation of the point spread function (PSF) of imaging systems in astronomy. Lossy compression algorithms reduce irrelevant information in image functions, and their application distorts the image function. Astronomical images have typical specific properties - high grayscale bit depth, size, noise occurrence and special processing algorithms. They belong to the class of scientific images as well as medical or similar. Their processing and compression is quite different from the classical approach of multimedia image processing. The influence of the JPEG2000 coder on the deformation of PSF is presented in this paper.
