Method för behandling av en digital bild och bildrepresentationsformat

摘要

The zeroth order coefficient of each data unit of an image block, is accessed. The Huffman decoding is not performed/performed to preset number of coefficients of data unit, so that the rest of the coefficient is skipped by jumping to next zeroth/first order coefficient in bitstream (36) using information (32) related to number of bits in bitstream between coefficients zeroth/first order in adjacent data unit. Independent claims are also included for the following: (1) image representation format; (2) method for encoding raw image data into compresses digital image representation; (3) method for analyzing JPEG-compressed digital image; and (4) method for stitching two digital images.
