Characterizations of rectangular (para)-unitary rational functions [PDF]
Opuscula Mathematica, 2016 We here present three characterizations of not necessarily causal, rational functions which are (co)-isometric on the unit circle: (i) through the realization matrix of Schur stable systems, (ii) the Blaschke-Potapov product, which is then employed to ...

Lossless polariton solitons [PDF]
Physica D: Nonlinear Phenomena, 2016 Photons and excitons in a semiconductor microcavity interact to form exciton-polariton condensates. These are governed by a nonlinear quantum-mechanical system involving exciton and photon wavefunctions. We calculate all non-traveling harmonic soliton solutions for the one-dimensional lossless system.

Backward adaptive pixel-based fast predictive motion estimation [PDF]
, 2009 This letter presents a novel backward adaptive pixel-based fast predictive motion estimation (BAPME) scheme for lossless video compression. Unlike the widely used block-matching motion estimation techniques, this method predicts the motion on a pixel-by ...

Lossless Image Compression by Joint Prediction of Pixel and Context Using Duplex Neural Networks
IEEE Access, 2021 This paper presents a new lossless image compression method based on the learning of pixel values and contexts through multilayer perceptrons (MLPs). The prediction errors and contexts obtained by MLPs are forwarded to adaptive arithmetic encoders, like ...

Lossless trace compression [PDF]
IEEE Transactions on Computers, 2001 The tremendous storage space required for a useful data base of program traces has prompted a search for trace reduction techniques. In this paper, we discuss a range of information-lossless address and instruction trace compression schemes that can reduce both storage space and access time by an order of magnitude or more, without discarding either ...

Lossless Data Embedding—New Paradigm in Digital Watermarking
EURASIP Journal on Advances in Signal Processing, 2002 One common drawback of virtually all current data embedding methods is the fact that the original image is inevitably distorted due to data embedding itself.
