Paper Abstract

We describe design of a low-complexity lossless and near-lossless image compression system with random access, suitable for embedded memory compression applications. This system employs a block-based DPCM coder using variable-length encoding for the residual. As part of this design, we propose to use non-prefix (one-to-one) codes for coding of residuals, and show that they offer improvements in compression performance compared to conventional techniques, such as Golomb-Rice and Huffman codes.
