Method of codebook generation for an amplitude-adaptive vector quantization system

摘要

The present invention relates to the field of vector quantization of transmitted imagery. In particular, the invention is a method for automatically generating a codebook for use in the transmitter and receiver components of an amplitude-adaptive normalized differential vector quantization system based upon a specified signal-to-noise ratio goal. In accordance with this method, the specified signal-to-noise ratio goal automatically derives the amplitude thresholds and other required data to determine the tradeoff between image quality and data compression for the transmitted imagery.
