Abstract

We present a simple but effective algorithm to accelerate the encoding process in a vector quantization scheme when a MSE criterium is used. A considerable reduction in the number of operations is achieved. This algorithm was first designed for image vector quantization in which the samples of the image signal (pixels) are positive, although it can be used with any positive-negative signal with only a minor modification.
