[PDF][PDF] Image sequence coding using adaptive finite-state vector quantization
JS Wang - IEEE Transactions on circuits and systems for video …, 1992 - cs.ccu.edu.tw
In the encoding of image sequences for transmission and storage, the coding algorithm must
have the ability to adapt to changing image characteristics from sequence to sequence and
from frame to frame. This paper describes a new adaptive finite-state vector quantization
(FSVQ) in which the bit rate and the encoding time can be reduced. In order to improve the
image quality and avoid producing a wrong state for an input vector, a threshold is used in
FSVQ to decide whether to switch to a full searching VQ. The codebook is conditionally …
