Performance analysis of the pyramid motion compensation based on quantization noise modeling

Abstract

We present in this paper the rate distortion performance analysis of the pyramid motion compensation for video spatial scalability. Theoretical performance function is derived in closed form based on quantization noise modeling. Evaluation of the rate distortion performance functions shows that, compared to intra-layer motion-compensated prediction coding the enhancement layer, pyramid method is expected to achieve more efficient compression if the base layer is encoded at a sufficient high quality, i.e., the encoded rate is high enough.
