A multichannel dynamic-range compressor system using digital frequency warping is described. A frequency-warped filter is realized by replacing the filter unit delays with all-pass filters. The appropriate design of the frequency warping gives a nonuniform frequency representation very close to the auditory Bark scale. The warped compressor is shown to have substantially reduced group delay in ...

Warped products provide perhaps the major source of examples and counterexamples in metric and Riemannian geometry. Sufficient conditions for a warped product B×f F to have a curvature bound in the sense of Alexandrov, either above or below, are found in [AB 04]. Given the importance of warped products, we want to know if all the known sufficient conditions are needed. Here we prove their neces...

We study holographic aspects of 2D dilaton-supergravity in flat space-time using gauge theoretic BF formulation. The asymptotic symmetries Bondi and at finite temperature span a supersymmetric extension the warped Virasoro algebra level zero. boundary action is determined such that bulk variational principle ensured turns out to be super-warped Schwarzian theory vanishing level. also thermodyna...

The interaction between the accretion stream and the thin, tilted and twisted accretion disk is found to be consistent with the observed complex dip structure in the X-ray signal of Her X-1. The stream falls into the warped disk mostly from above or below where the hydrodynamic interaction leads to a cold clumpy spray covering the X-ray source once per orbit. We test this model with the warped ...

The goal of this project is to develop a portable structured light scanner which can capture the 3D structure of arbitrarily warped printed text and then rectify it. The resulting rectified text can then be sent to a standard OCR engine for recognition and layout analysis. The rectified image of the text can also be used as a reference image for non-rigid surface detection. Pairing non-rigid su...

Along with images and videos, 3D models have recently gained increasing attention for a number of reasons: advancements in 3D hardware and software technologies, their ever decreasing prices and increasing availability, affordable 3D authoring tools, and the establishment of open standards for 3D data interchange. In this paper we address the problem of content-based retrieval of 3D models. The...
