In this paper, we introduce a new motion vector prediction method that could be used within multiple picture reference codecs, such as the H.264 (MPEG-4 AVC) video coding standard. Our method considers for each candidate motion vector the temporal distance of its corresponding reference picture compared to the current one for the generation of the predictor motion vector. This allows for more a...

The purpose of this paper is to provide an algorithm for the motion picture companies to evaluate the key capabilities from firm viewpoint under fuzzy environment. The fundamental concepts we have adopted include the eigenvector method, fuzzy Delphi method, fuzzy set theory, and multi-criteria decision making method. With the concept of balanced scorecard and the interviewing managers of motion...

Using a stochastic representation provided by Wiener-regularized path integrals for the semigroups generated by certain Berezin-Toeplitz operators, a transformation formula for their resolvents is derived. The key property used in the transformation of the stochastic representation is that, up to a time change, Brownian motion is invariant under harmonic morphisms. This result for Berezin-Toepl...

Digital technologies and, especially, the Internet are profoundly reshaping the motion picture industry. Video-on-demand heightens the trend toward digitization and disintermediation. In the short term, the increasing use of digital technologies may result in significant cost reductions throughout the value chain. In the long term, the digitization of film production and distribution may induce...

The rapid and detailed recognition of human action from point-light displays is a remarkable ability and very robust against masking by motion signals. However, recognition of biological motion is strongly impaired when the typical point lights are replaced by pictures of complex objects. In a reaction time task and a detection in noise task, we asked subjects to decide if the walking direction...

We consider solutions of the Schrödinger equation with a weak time-dependent random potential. It is shown that when the two-point correlation function of the potential is rapidly decaying, then the Fourier transform ζ̂ε(t, ξ) of the appropriately scaled solution converges point-wise in ξ to a stochastic complex Gaussian limit. On the other hand, when the two-point correlation function decays sl...

Prelude: In almost every environment, there exists a microbe that has evolved a mechanism(s) to exploit that niche. The mammalian host represents a potentially rich environment for the growth of mesophilic organisms. However, the host has evolved specific innate and acquired mechanisms to prevent (or limit) growth. Pathogens have evolved to exploit this nutrient rich environment in the context ...

Let u(x, t) be the solution of the Schrödinger or wave equation with L 2 initial data. We provide counterexamples to plausible conjectures involving the decay in t of the BMO norm of u(t, ·). The proofs make use of random methods, in particular, Brownian motion.

We consider solutions of the Schrödinger equation with a weak time-dependent random potential. It is shown that when the two-point correlation function of the potential is rapidly decaying then the Fourier transform ζ̂ε(t, ξ) of the appropriately scaled solution converges point-wise in ξ to a deterministic limit, exponentially decaying in time. On the other hand, when the two-point correlation f...
