VDII ~ I A new CMOS buffer is introduced. A compensation circuit is used to cancel the output voltage offset resulting from the body effect. The voltage offset cancellation is achieved over all the input range hence resulting in a highly linear voltage transfer gain, which is independent of process variation. Class AB output stage is used in order to minimize the power consumption and increase ...

This paper deals with the coding of the partition information resulting from the segmentation of video se quences Motion compensation of partition sequences is described as an e cient inter frame mode of coding It involves the prediction of the partition the computation of the partition compensation error the simpli cation of the error and its transmission The major issues and processing steps ...

Video compression has been an active research area in the last decade. Amongst many proposed methods, motion compensated coding has taken the most attention and taken its place in many standards (Mpeg, H.26L, etc...) The main difference between motion compensated coding and image based coding schemes such as DCT is that motion compensated coding exploits temporal redundancies between consecutiv...

Multihypothesis motion-compensating predictors combine several motion-compensated signals to predict the current frame signal. More than one motion-compensated signal, or hypothesis, is selected for transmission. Long-term memory motion-compensated prediction is a further concept for efficient video compression and is an example for forward-adaptive hypothesis switching. One motion-compensated ...

This article explores the efficiency of motion-compensated three-dimensional transform coding, a compression scheme that employs a motion-compensated transform for a group of pictures. We investigate this coding scheme experimentally and theoretically. The practical coding scheme employs in temporal direction a wavelet decomposition with motion-compensated lifting steps. Further, we compare the...
