In this paper, a new method of saliency-based traffic sign detection is presented. On the basis of the visual attention mechanism model, edge and color information are extracted as early visual features, and each feature is computed and normalized to obtain feature maps, conspicuity maps and the saliency map. Then the candidate regions containing traffic signs are determined with self-organizing map...
it presents a method of AADL reliability analysis and assessment for embedded systems in this paper. The system reliability is not only relies on system architecture, but also relates to dynamic behavior of system model. Based on behavior model, it generates error model automatically which has been widely used in reliability modeling and analysis, and this reflects the association between error happening...
The development trend of E-Business is the P2PEB. In this mode, trust is the base to guarantee the normal conduction of the business activity. According to the features of trust between Enterprises, we propose a double layers trust system in P2PEB mode named as DL-Trust System. After explaining the different mechanisms of the direct trust and indirect trust and discussing the interaction of the double...
This paper firstly tell the basic theory and technology of TRIZ which supports for computer-aided innovation. Then one new computer-aided innovation system based on knowledge discovery is given in this paper. The system try to simulate the thinking process of human in the innovation which can short the innovating hours. Finally the main functions of this system are descriptive. This system provide...
This paper describes a scalable parallel method for interferometric synthetic aperture radar (InSAR) raw data simulation on graphic processing unit (GPU) with common unified device architecture (CUDA). The advantages of the new method rely on the three contributions: GPU hardware provides lots of stream processors for threads calculating, CUDA software environment runs thousands of threads working...
With the development of parallel technology and application, the performance analysis and visualization of parallel computing is one of the most important parts. This paper presents a parallel computing performance visualization system which is developed to visualize and analyze the speedup and efficiency of parallel computing. We visualize and analyze the results of magnetotelluric parallel forward...
In this paper we present a raw signal simulator based on GPU parallel computation for synthetic aperture radar. We describe a mathematical model of SAR simulation based on FFT in detail and implement it through GPU parallel computation. GPU has a better performance in complex calculation than CPU. It supports parallel computation and raises the speed of algorithms. At the last part of this paper,...
