A Fast Encoding Algorithm for Vector Quantization Using Difference Pyramid Structure

This paper proposed a fast vector quantization encoding algorithm called difference pyramid search (DPS). According to the formation of the difference pyramid and partial distortion elimination, a rejection test inequality is derived to progressively reject a lot of nonclosest code words as early as...
