Tracking pixels in videos is typically studied as an optical flow estimation problem, where every pixel described with a displacement vector that locates it the next frame. Even though wider temporal context freely available, prior efforts to take this into account have yielded only small gains over 2-frame methods. In paper, we revisit Sand and Teller’s “particle video” approach, study trackin...

Deduce an expression for the rate of precession of the spin polarization unit vector P̂ of a relativistic charged particle in laboratory electric and magnetic fields E and B. The polarization vector is to be measured in the so-called comoving rest frame of the particle obtained by boosting from the lab frame along the direction l̂ that is tangent the the particle’s laboratory trajectory, and whos...

Many purely neural network based speech separation approaches have been proposed to improve objective assessment scores, but they often introduce nonlinear distortions that are harmful modern automatic recognition (ASR) systems. Minimum variance distortionless response (MVDR) filters adopted remove distortions, however, conventional mask-based MVDR systems still result in relatively high levels...

In this paper, we extend Sasaki metric for tangent bundle of a Riemannian manifold and Sasaki-Mok metric for the frame bundle of a Riemannian manifold [I] to the case of a semi-Riemannian vector bundle over a semi- Riemannian manifold. In fact, if E is a semi-Riemannian vector bundle over a semi-Riemannian manifold M, then by using an arbitrary (linear) connection on E, we can make E, as a...

Traditional plane alignment techniques are typically performed between pairs of frames. In this paper we present a method for extending existing two-frame planar-motion estimation techniques into a simultaneous multi-frame estimation, by exploiting multi-frame geometric constraints of planar surfaces. The paper has three main contributions: (i) we show that when the camera calibration does not ...

This paper presents multi-frame rate volume rendering, an asynchronous approach to parallel volume rendering. The workload is distributed over multiple GPUs in such a way that the main display device can provide high frame rates and little latency to user input, while one or multiple backend GPUs asynchronously provide new views. The latency artifacts inherent to such a solution are minimized b...
