Traditional visual place recognition (VPR), usually using standard cameras, is easy to fail due glare or high-speed motion. By contrast, event cameras have the advantages of low latency, high temporal resolution, and dynamic range, which can deal with above issues. Nevertheless, are prone failure in motionless scenes, while still provide appearance information this case. Thus, exploiting comple...

We give lower frame bounds for finite subfamilies of a frame of exponentials {ek}k∈Z in L2(−π, π). We also present a method for approximation of the inverse frame operator corresponding to {ek}k∈Z, where knowledge of the frame bounds for finite subfamilies is crucial.

For each pair (n, k) with 1 </= k < n, we construct a tight frame (rholambda : lambda in Lambda) for L2 (Rn), which we call a frame of k-plane ridgelets. The intent is to efficiently represent functions that are smooth away from singularities along k-planes in Rn. We also develop tools to help decide whether k-plane ridgelets provide the desired efficient representation. We first construct a wa...

Nonlinear state estimation and fusion tracking are always hot research topics for information processing. Compared to linear fusion tracking, nonlinear fusion tracking takes many new problems and challenges. Especially, the performances of fusion tracking, based on different nonlinear filters, are obviously different. The conventional nonlinear filters include extended Kalman filter (EKF), unsc...

BACKGROUND To evaluate the effect of spondylolisthesis on lumbar lordosis on the OSI (Jackson; Orthopaedic Systems Inc.) frame. Restoration of lumbar lordosis is important for maintaining sagittal balance. Physiologic lumbar lordosis has to be gained by intraoperative prone positioning with a hip extension and posterior instrumentation technique. There are some debates about changing lumbar lor...

The relay fusion frame proposed by Hong and Li is an extension of a that has many applications in science. In this study, we introduce frames Hilbert C ∗ -modules very naturally shift some common attributes spaces to id="M4"> -modules. addition, generalize perturbation results theor...

An approach is presented to multi-expert’s opinions combination based on the Dempster-Shafer evidence theory. In the method, we use multi-expert’s knowledge as evidence, the possible value of weight as frame of discernment, expert’s evaluation to a weight on frame of discernment as basic probability assignment, and use D-S rule combining to give fusion basic probability assignment m. Finally, t...

Background and Aims: Since the produced recombinant proteins by molecular genetics techniques commonly have some limitations in the application, chimeric protein are introduced. Chimeric proteins have found widespread application for the study of protein folding, structure stability, function and immunogenisity. Methods: According to the known Immunomodulatory effect and structure of HSP70 mole...

For tracking accuracy of moving target in wide-area video surveillance system is not high, a tracking and recognition algorithm based on multi-source moving target is proposed. The fusion algorithm preliminarily determines candidate moving target by frame difference algorithm, and then matches candidate target with primary template by SIFT algorithm and treats the matching result as initial pos...
