Fast ITTBC Using Pattern Code on the Subband Segmentation

Abstract

Iterated Transformation Theory-Based Coding(ITTBC) suffers from very high computational complexity in encoding phase. This is due to its exhaustive search. In this paper our proposed image coding algorithm preprocess an original image to subband segmentation image by wavelet transform before image coding to reduce encoding complexity. A similar block is searched by using the 24 block pattern codes which are coded by the edge information in the image block on the domain pool of the subband segmentation. As a result Numerical data shows that the encoding time of the proposed coding method can be reduced to 98.82% of that of Jacquin's method, while the loss in quality relative to the Jacquin's is about 0.28dB in PSNR, which is visually negligible.
