Abstract

This paper propose a novel vector-quantized block truncation coder for image data compression. A data compression ratio of about 3-6 times larger than that of the BTC can be achieved by utilizign a vector quantizer with the BTC. A vector quantizer was realized by computer simulation. The compressed data rate of 0.7~1.0 bit/pel with intraframe coder and that of 0.3~0.5 bit/pel with interframe coder gives a good performance.
