Visualization of Vector Quantization

Abstract:- In this paper, a novel scheme for vector quantization (VQ) is proposed. A file called visible index file is used to record the coding result. The decompressed image reconstructed from the visible index file is the same as the one recovered using traditional VQ index file; however, the visible index file looks like the original image, and is therefore more convenient for the management of index files. Also, note that the size of the visible index file is the same as that of the traditional index file. Key-words: vector quantization, sorted codebook, visible index files.
