Abstract:
1. A method of determining image compression suitability, using an image compression device, comprising: performing, by the image compression device, a compression process on an uncompressed image to generate a compressed image of said uncompressed image whereby said uncompressed image and compressed image are divided into blocks; gathering data from said compression process on said uncompressed image by the image compression device; performing an error metric analysis with said data by the image compression device; checking each of said blocks in said uncompressed image and compressed image by the image compression device; in addition to performing error metric analysis on the compressed image, also performing error metric analysis on blocks of the uncompressed image; and in response, deciding, by the image compression device, based on a count of said blocks that fail the checks, which of said uncompressed image or said compressed image is a suitable representation of said uncompressed image for storage and/or transmission based on the error metric analyses on the compressed image and the uncompress image.
