摘要: This paper describes source encoding of the outputs a block truncation coder (BTC), namely, overhead statistical information and truncated block. The exhibit properties which can be effectively used for their quantization as vectors. Vector these BTC results into reduction bit rate coder. reduces up to 1.5 bits/ pel if vector is on one outputs; i.e., either or By quantizing both he reduced 1.0 bits/pel without introducing many perceivable errors in reconstructed output.
