Abstract
A method of automatically compressing and decompressing a digital image that is comprised of the following steps: acquiring a digital image through an image acquisition system; generating a look-up-table (companding function) based upon noise characteristics of the image acquisition system; applying the companding function to the image; processing the image using a lossless compression algorithm; reconstructing the image using the associated decompression algorithm; and applying the inverse of the companding function to the image.
