This paper proves that every frame of windowed exponentials satisfies a Strong Homogeneous Approximation Property with respect to its canonical dual frame, and a Weak Homogeneous Approximation Property with respect to an arbitrary dual frame. As a consequence, a simple proof of the Nyquist density phenomenon satisfied by frames of windowed exponentials with one or finitely many generators is ob...

We consider the problem of recovering fusion frame sparse signals from incomplete measurements. These signals are composed of a small number of nonzero blocks taken from a family of subspaces. First, we show that, by using a-priori knowledge of a coherence parameter associated with the angles between the subspaces, one can uniformly recover fusion frame sparse signals with a significantly reduc...

Levin’s MLS projection operator allows defining a surface from a set of points and represents a versatile procedure to generate points on this surface. Practical problems of MLS surfaces are a complicated non-linear optimization to compute a tangent frame and the (commonly overlooked) fact that the normal to this tangent frame is not the surface normal. An alternative definition of Point Set Su...

A method for creating and presenting video-recorded synchronized audiovisual stimuli at a high frame rate-which would be highly useful for psychophysical studies on, for example, just-noticeable differences and gating-is presented. Methods for accomplishing this include recording audio and video separately using an exact synchronization signal, editing the recordings and finding exact synchroni...

The video retrieval system we developed for TRECVID 2012 mainly involves the semantic indexing task which includes key frame extraction, low level feature extraction, classification and concept fusion. We extracted a new low level feature, explored various classification and fusion schemes. Four “light” runs and two 2 “pair” runs we submitted are as follows: L_A_FudaSys1: Fusion based on concep...

BACKGROUND The formation of fusion genes plays roles in both oncogenesis and evolution by facilitating the acquisition of novel functions. Here we describe the first example of a human polymorphic in-frame fusion of two unrelated genes associated with a copy number variant. DESIGN AND METHODS Array comparative genomic hybridization was used to identify cryptic oncogenic fusion genes. Fusion g...

Recently, fusion frames and for operators were considered as generalizations of in Hilbert spaces. In this paper, we generalize some the known results frame theory to related a linear bounded operator K which call K-fusion frames. We obtain new by considering with class construct from given ones. also study stability under small perturbations. further give characterizations atomic systems subsp...

Grid computing is used to realize the connection of distributed, heterogeneous computing resources through grid, assist in accomplishing computing task. Focusing on the weakness of centralized information fusion, put forward the disturbed fusion model utilizing grid computing node to realize local decision fusion on the basis of distributing information fusion architecture, and transform the de...

Video-based person recognition is challenging due to persons being blocked and blurred, the variation of shooting angle. Previous research always focused on still images, ignoring similarity continuity between video frames. To tackle challenges above, we propose a novel Frame Aggregation Multi-Modal Fusion (FAMF) framework for video-based recognition, which aggregates face features incorporates...
