| Abstract |
This is a contribution for very low bit rate video coding in
real-time and software only on computers of PC class. It
is based on frame replenishment with block coding using
mean-removed vector quantization. No motion compensa-
tion is employed and the VQ codebook is small. Algorithms
are developed to minimize the bit rate and to reduce the
search complexity for the vector quantizer. The codebook is
adaptive ensuring good overall quality encodings for head-
and-shoulder image sequences. Results are provided for
some test sequences and compared to some other state-of-
the-art techniques. |
