Abstract
A method for reversible coding of an image, including extracting compression information from an image compressed in an original format, at least partly decompressing the compressed image into an intermediate at least partly decompressed image, re-encoding the intermediate image into a re-encoded image, and preferably associating in a same file, the re-encoded image with compression information.
