Title |
Rate-distortion based video coding with adaptive mean-removed vector quantization |
Abstract |
In this paper we improve the rate-distortion performance of
a previously proposed video coder based on frame replenishment
and adaptive mean-removed vector quantization.
This is realized by determining for each block of a given
frame the optimal encoding mode in the rate-distortion sense.
The algorithm is a new contribution to very low bit rate
video coding with adaptive vector quantization suitable for
videophone applications. Experimental results comparing
the two coders for several test sequences at different bit
rates are provided. |
