Fast Encoding Algorithm for Vector Quantization- Based on Block Truncation Coding Technique

An adaptation will he used to improve the compressibility of the BTC by utilizing the VQ method to represent the binary form of the coded image produced from the BTC. 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. In our presence work, a fast algorithm for vector quantizing image data is proposed The algorithm is proved powerful.
