Novel word-level algorithm of embedded block coding in JPEG 2000
In this work, a novel word-level algorithm of the embedded block coding in JPEG 2000 is proposed. Unlike conventional approaches, all bitplanes of coefficients are processed in parallel in the proposed algorithm. The algorithm is based on the observations and the analysis of the significant state of a coefficient and its contribution to neighbors. As a result of the analysis, there is only the coding pass of the MSB of a coefficient is the required information for the word-level processing. An algorithm for finding the coding pass of the MSB of a coefficient is also proposed. The number of scans of the entire code block is reduced to two scans and is independent of the number of bit planes.
