A new method of detecting moving object in dynamic background is proposed in this paper. At first, an adaptive threshold Harris algorithm is proposed in this paper to extract feature points, then, SIFT algorithm is used to describe these extracted feature points. The similarity function is used to match feature points and RANSAC algorithm is used to eliminate the pseudo matches. According to the correct...
Unknown values (Xs) may exist in a design due to uninitialized registers or blocks that are powered down. Due to limitations known as X-optimism and X-pessimism, such Xs cannot be handled correctly in logic simulation, producing inaccurate simulation values that can mask X bugs or corrupt simulation results. This can cause X bugs to escape verification and reduces design quality. To resolve such X-related...
In this paper, by means of the thought of software reverse engineering, according to the practical problem that the difficulties of analysis and explaining by teachers, and students are not easy to understand the knowledge, it applies the computer multi-media visualization technology, researches the related technologies and methods which demonstrate dynamically and interactive operation in the CAI...
The Vehicle Routing Problem (VRP) is a NP complete problem and is also a hot topic in the operational research. But traditional methods might suffer from slow convergence and the curse of large sizes, heuristics-based swarm intelligence can be an efficient alternative. Particle swarm optimization (PSO) is known to effectively solve engineering optimization problems. In this paper, the PSO in solving...
Grid computing is a new arising technology which gets computer from different locations to work together with various data resources. Because of its high capability, grid has contributed to a plenty of areas. When computing for a special objective, typically a series of algorithms are needed. As conventional algorithm bases were built for just specific areas, a multifunctional grid-algorithm-base...
Reconfiguration latency is an important factor which impacts the system performance in the reconfigurable computing design. In this paper, a framework is proposed that presents a novel approach for an optimal implementation of algorithms on FPGA based reconfigurable system. The method optimizes the temporal partitioning by performing a similar-rate-computing-based architectural synthesis. It gives...
