Theoretical and experimental results for motion-compensated linear prediction of video signals are presented. T h e rate distortion theory of motion-compensated prediction is extended to linear predictive models. For practical implementations, linear vector predictors are employed. The rate of the motion data is ccmtrolled by minimizing a Lagrangian cost function whore rate is weighted against ...

The anisotropies in the galaxy two-point correlation function measured from redshift surveys exhibits deviations from the predictions of the linear theory of redshift space distortion on scales as large as 20 h Mpc where we expect linear theory to hold in real space. Any attempt at analyzing the anisotropies in the redshift correlation function and determining the linear distortion parameter β ...

Linear and projective boundaries of Cayley graphs were introduced in [6] as quasi-isometry invariant boundaries of finitely generated groups. They consist of forward orbits g D 1g W i 2 No, or orbits g D 1g W i 2 Zo, respectively, of non-torsion elements g of the group G, where ‘sufficiently close’ (forward) orbits become identified, together with a metric bounded by 1. We show that for all fin...

We propose the application of two-dimensional distortion models for comparisons of medical images in a distance-based classifier. We extend a simple zero-order distortion model by using local context within the compared image parts. Vertical and horizontal image gradients as well as small sub images are used as local context. Taking into account dependencies within the displacement field of the...

Consider a scenario in which the data owner has some private/sensitive data and wants a data miner to access it for studying “important” patterns without revealing the sensitive information. Privacy preserving data mining aims to solve this problem by randomly transforming (distorting) the data prior to its release. Previous work only considered the case of linear distortions — additive, multip...

This paper shows how intermodulation distortion, IMD, sweet spots can be used as a practically meaningful technology to design highly linear microwave power amplifiers. It starts by reviewing the physical origins of these points of large signal to nonlinear distortion ratio, distinguishing the ones uniquely determined by the active device’s quiescent point – small-signal IMD sweet spots – from ...

ethan kohlberg, the jewish orientalist and specialist on shi‘a, sees the distortion in holy scriptures, including quran, inevitable. from his point of view, some quranic verses confirm this point. his second proof is the history of the quran and the time when its whole text was written down. in his viewpoint,   hadiths which prove that the quran had been written down in abu bakr’s time ore orie...

Computing a bijective spherical parametrization of a genus-0 surface with low distortion is a fundamental task in geometric modeling and processing. Current methods for spherical parametrization cannot, in general, control the worst case distortion of all triangles nor guarantee bijectivity. Given an initial bijective spherical parametrization, with high distortion, we develop a non-linear cons...

In this paper, a least distortion approach is proposed for halftone image watermarking. The impacts of distortion and tonality problems in halftoning are analyzed. An iterative linear gain model is developed to optimize perceptual quality of watermarking halftone images with efficient computation complexity O(1). An optimum linear gain for data hiding error diffusion is derived and mapped into ...
