摘要
The encoding of a VQ-based image coding requires a full codebook search for each input vector to find out the best matched codeword. It is a time consuming process. A fast algorithm for vector quantising image data is proposed. The algorithm is proved powerful. © 1990, The Institution of Electrical Engineers. All rights reserved.
