Raster and vector are two major types of data format in GIS, we often need to make a conversion of raster data to vector considering the advantages of vector. In this paper we first discuss the classic algorithms of vectorization and the technology of high performance computing, by applying the parallel strategy to vectorization algorithm, we present a specific parallel algorithm for polygon vectorization...
There is a significant interest in the research community to develop large scale, high performance implementations of neuromorphic models. These have the potential to provide significantly stronger information processing capabilities than current computing algorithms. In this paper we present the implementation of five neuromorphic models on a 50 TeraFLOPS 336 node Playstation 3 cluster at the Air...
We present a new optimization-based reconstruction model with geometric feature-preserving regularization. The previous construction approach of optimization-based requires generally solving a tremendously large discrete linear system. In addition, the analytic algorithms, such as, back-projection related methods, Fourier transform based reconstruction algorithms, are sensitive to noise. These disadvantages...
Multi-motor synchronous system is being widely applied in industrial field, in order to ulteriorly improve synchronous performance of multi-motor system, this paper presents a synchronous control system for three-motor which includes three intelligent PID controllers based on BP neural network arithmetic which adjusts the parameters of PID controllers on-line, and neuron decoupling compensator fulfilling...
