ABSTRACT:
A system and method for discriminating among image characteristics in order to select among a plurality of compression techniques. Multiple compression schemes are applied to a source image (101) concurrently and the results are stored. Image discrimination is performed in parallel with the image compression to generate a recommendation regarding the stored compressed images.
