Abstract
A hybrid block truncation coding (BTC) is presented. In the hybrid BTC, a universal codebook using Hamming codes and a differential pulse code modulation (DPCM) are employed, respectively, to the bit plane and the side information of BTC to reduce coding rate. Simulation results reveal that the performance of the proposed algorithm is only slightly worse than that of the hybrid BTC using vector quantization (VQ) techniques, but with much lower computational or hardware complexity.
