Fast vector quantization algorithm - based on Absolute Moment Block Truncation coding (AMBTC)

ABSTRACT An development will be used to improve the compressibility of the AMBTC using the VQ method to represent the binary form of the coded image produced from the AMBTC. The encoding of a VQ image coding requires a full codebook search for each input vector to find out the best-matched codeword. It is a time consuming process. In our presence work, a fast algorithm for vector quantizing image data is proposed. The algorithm is proved powerful.
