Improved moment preserving block truncation coding for image compression
Yu‐Chen Hu · Electronics Letters · 2003
A novel image compression scheme based on moment preserving block truncation coding (MPBTC) is introduced. To reduce the bit rate of the traditional MPBTC scheme, the block search order coding technique is employed to exploit the similarity among neighbouring image blocks. In addition, smooth blocks and complex blocks are processed using different methods. Experimental results show that the proposed scheme provides good image quality at a low bit rate.
