Based on minimum reconstruction error criterion and the intrinsic sparse property of natural data, sparse representation (SR) has shown promising performance on various image recognition tasks. However, in the field of person re-identification (re-id), the state-of-the-art is still dominated by other methods such as metric learning or CNN. It is because samples in one view may not be representative...
IP Multimedia Subsystem (IMS) is mostly regarded as the core architecture of the next generation network. And the mobile video call service based on IMS network is almost sure to be one of the most important applications beyond the 3rd generation mobile communication. This paper focuses on design and implementation of IMS video call based on Windows Mobile system and the open source eXosip package...
We extend a recent Sparse Representation-based Classification (SRC) algorithm for face recognition to work on 2D images directly, aiming to reduce the computational complexity whilst still maintaining performance. Our contributions include: (1) a new 2D extension of SRC algorithm; (2) an incremental computing procedure which can reduce the eigen decomposition expense of each 2D-SRC for sequential...
High Level Architecture (HLA) is the new standard of distributed simulation. Being short of Integrated Environment of Modeling and Simulation, it is difficult to develop complex simulation systems based on HLA. KD-HLA is designed as an environment for distributed simulation using the standard of HLA. It includes three parts: Federation Design and Developing Environment, Federation Execution and Control...
The paper presents the construction and principle of a designed system for diagnostic testing of high voltage circuit breakers (CB). The diagnostic testing system of circuit breakers is performed by characteristic analysis, and the discrete-time Mallet wavelet transform algorithm is used to process the signal of coil current. The coil current characteristic patterns from circuit breakers (made by...
Feature detection and display are the essential goals of the visualization process. Most visualization software achieves these goals by mapping properties of sampled intensity values and their derivatives to color and opacity. In this work, we propose to explicitly study the local frequency distribution of intensity values in broader neighborhoods centered around each voxel. We have found frequency...
Federations based on HLA should conform to a series of rules and be able to exchange data effectively through Run Time Infrastructure (RTI). Therefore, it is necessary to design effective Federate Compliance Test Software (FCT) to test federate, which assure the correctness of federates. Existing federate compliance test approaches that adopted dynamic compiling methods are difficult and complicated...
