Computational RAM implementation of an adaptive vector quantization algorithm for video compression

Abstract

Vector quantization (VQ) is a promising technique for low-bit rate image and video compression. Adaptive VQ-based video compression algorithms have been reported in the literature. This paper proposes an adaptive codebook replenishment VQ algorithm using index-based motion estimation (AVQ+ME) for low-bit rate video compression. The proposed technique has been implemented on a computational* RAM (C*RAM) SIMD structure.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
