A method of decompressing a document image compressed with JPEG ADCT and a subsequent statistical encoding method, includes an iterative processing step, which filters the image to correct for compression/decompression artifacts, and subsequently checks the ADCT coefficients of the filtered image to determine whether the filtered image is a possible one, given the received original ADCT coefficients and Q-Table description. In such an arrangement, the iterative process step can be terminated at a preselected number of iterations based on the measured size of the statistical encoding prior to removing the statistical encoding.
