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...

Abstract Out-of-step oscillation separation devices based on apparent impedance angle trajectory are widely used in the power grid China, and their reliability is of great importance. In this paper, influence mechanism series compensation analyzed. It reveals that capacitors reduce equivalent consequently cannot pass through all four zones, resulting risk failure for devices. A revised method p...

Fully compensated ferrimagnetic half metals have attracted great attention in spintronics. Unlike many previous calculations based on hypothetical ordered alloys, here we look for existing solid solution series taking as an example Co 1− x Cr S 2 . Calculations find that a low-spin state matches early experiments and fully metal with Curie temperature above room is found at ≈ 0.33. Our study de...

This paper analyses the design of a controlled variable inductor adopted as series inductance an LCC-S compensation network in Inductive Wireless Power Transfer system. In this topology, power transfer to load can be by varying differential component through DC bias. The analytical process double E ferrite core is presented, and specifications for experimental prototype are proposed. output ver...

This paper presents an efficient method based on bus power injection for transmission line compensation. In this method, the load flow solution is first obtained using specified generations and loads. The terminal buses connecting the line to be compensated and the compensation level are identified. The differences of the line flows before and after compensation are injected in or out of the tw...

From the partial differential Calogero’s (three-body) and Smorodinsky-Winternitz (superintegrable) Hamiltonians in two variables we separate the respective angular Schrödinger equations and study the possibilities of their “minimal” PT symmetric complexification. The simultaneous loss of the Hermiticity and solvability of the respective angular potentials V (φ) is compensated by their replaceme...
