In this paper, a critical analysis of the joint source channel coding scheme proposed by Honary et al.1 is given. We show mathematically that although the algorithm leads to a reduction in the overall number of decoding states it increases both the time and space complexity of the decoding ...
One suboptimal but reduced-complexity finite Huffman coding example is disclosed in U.S. Patent No. 4,560,976, entitled “Data Compression” and issued Dec. 24, 1985 to Finn. Finn describes a finite codebook consisting only of one-, two-, and three-subword-long codewords. Finn uses a ...

This realizes the time variability of compression coding stream (CCS) of an image in that the image TV-HCT has large change space. Analysis shows that the average change space of TV-HCT in UCID is 3.97脳10327, and the average ER of three databases is more than 0.44 bpp higher than the...
Then, Huffman coding is used to compress the tag map so that a large amount of vacant space is obtained. Finally, the secret data can be embedded into the vacated space by directly using bit substitution. Compared with some recently reported methods, experimental results and analysis have ...
As the size of the block increases, the variant-Huffman coding approaches the entropy limit. However, there are some theoretical difficulties. For instance, first, the time complexity of the algorithm becomes exponential with regard to the size of the block, which makes the approach impractical. ...
