High-Performance Compression of Astronomical Images

  title={High-Performance Compression of Astronomical Images},
  author={Richard L. White},
Astronomical images have some rather unusual characteristics that make many existing image compression techniques either ine ective or inapplicable. A typical image consists of a nearly at background sprinkled with point sources and occasional extended sources. The images are often noisy, so that lossless compression does not work very well; furthermore, the images are usually subjected to stringent quantitative analysis, so any lossy compression method must be proven not to discard useful… CONTINUE READING
