In video surveillance, there are many interference factors such as target changes, complex scenes, and target deformation in the moving object tracking. In order to resolve this issue, based on the comparative analysis of several common moving object detection methods, a moving object detection and recognition algorithm combined frame difference with background subtraction is presented in this ...

Let M be a smooth compact oriented Riemannian manifold, and let ∆ be the Laplace-Beltrami operator on M. Say 0 6= f ∈ S(R), and that f(0) = 0. For t > 0, let Kt(x, y) denote the kernel of f(t∆). Suppose f satisfies Daubechies’ criterion, and b > 0. For each j, write M as a disjoint union of measurable sets Ej,k with diameter at most ba j , and comparable to ba if ba is sufficiently small. Take ...

We establish a regular sampling theory in the range of analysis operator continuous frame having unitary structure. The structure is related with representation locally compact abelian group on separable Hilbert space. samples are defined by means suitable discrete convolution systems which generalize some usual settings; here that taken at countable subgroup.

Hunton et al. (2008) observed a functional effect of continuous monitoring (real earnings management was eliminated) and a dysfunctional effect (intertemporal investment risk appetite was unduly diminished). Intertemporal investment risk appetite refers to managers’ willingness to invest or disinvest in and continue or discontinue with an ongoing long-term risky project. The current study exami...

It is well-known that the linear scale-space theory in computer vision is mainly based on the Gaussian kernel. The purpose of the paper is to propose a scale-space theory based on B-spline kernels. Our aim is twofold. On one hand, we present a general framework and show how B-splines provide a flexible tool to design various scale-space representations: continuous scalespace, dyadic scale-space...

A polyhelix is continuous space curve with continuous Frenet frame that consists of a sequence of connected helical segments. The main result of this paper is that given n points in space, there exist infinitely many polyhelices passing through these points. These curves are by construction continuous with continuous derivatives and are completely specified by 3n numbers, i.e., the initial posi...

In  this  paper  a  new  method  is  presented  for  structural  damage  identification.  First,  the damaged structure is  excited by short  duration impact acceleration  and then, the  recorded structural displacement time history responses under free vibration conditions are analyzed by Continuous Wavelet Transform (CWT) and Wavelet Residual Force (WRF) is calculated. Finally, an effective d...

The structure of binary coproducts in the category of frames is analyzed, and the results are then applied widely in the study of compactness, local compactness (continuous frames), separatedness, pushouts and closed frame homomorphisms.
