The latest high efficiency video coding (HEVC) standard achieves about 50% bit-rate reduction at equivalent visual quality compared to H.264/AVC. Sample adaptive offset (SAO) is one of the newly adopted tools right after deblocking filter, which can improve both coding efficiency and visual quality. However, for real-time encoding scenarios, the complexity of SAO is usually too high to be enabled...
Aviation network is the typical information network, where the airports can be regarded as nodes, and the airlines between airports can be regarded as links. But with the constraints with the Degree-Centrality, Closeness-Centrality and the Centrality between nodes, traditional researches on the influence of the information network developed slowly. Thus, we do some experiments on the traditional methods...
The emerging cloud gaming technology has been growing fast, driving up huge mobile consumer demands. The video streaming based cloud gaming scenario renders the game scenes in the cloud servers, and streams the encoded sequences to the thin clints where the game scenes are decoded and displayed to the players. However, current existing clouding gaming services have some problems, such as the latency...
This paper analyzes the gray projection motion vector estimation algorithm to illustrate the application environment and the characteristics of this algorithm, Indicate the needed of resources when implemented in hardware circuitry. Point at the Characteristics of the algorithm we made the corresponding optimized to make it more suitable for the hardware calculation. We design the corresponding circuit...
By taking into account communication startup overhead and the assigned processor distribution order and by applying hashing technique, a novel sequence distribution strategy is presented and the parallel local alignment algorithm for multiple sequences is designed on the heterogeneous cluster system that the computing nodes have different computing speeds and communication capabilities based on divisible...
This paper proposes a new parallel search algorithm using an evolutionary algorithm and quasi-simplex techniques (EAQST) for non-linear constrained function optimization. EAQST produces the offspring in parallel by using the Gaussian mutation, the Cauchy mutation and the quasi-simplex technique. Experimental studies on typical benchmark functions have shown that EAQST has very better performance than...
Web service composition is an important technology in domain of Web service. It provides an effective solution to complex Web application. In this paper, a new composition algorithm of semantic Web service based on QoS is proposed, which is concerned with the effect of some non-functional factors of service composite quality and the satisfaction with service composition. Experiments are carried out...
