Application of multiresolution vector quantisation to scaleable low bitrate and video coding

Bober M., Ciepliński L.

Vol. 4, no 1-2

25-35

A hybrid video codec employing multiresolution vector quantisation of intra-mode frames and DCT-based encoding of inter-mode framers is presented. The performance of the proposed technique is compared to the MPEG-4 video Verification Model version 4.0 and the TMN-2.0 implementation of the H.263 standard. The result show a significant performance improvement both in terms of signal to noise ratio and subjective visual quality.
