In this paper, we investigate the visual attention modeling for stereoscopic video from the following two aspects. First, we build one large-scale eye tracking database as the benchmark of visual attention modeling for stereoscopic video. The database includes 47 video sequences and their corresponding eye fixation data. Second, we propose a novel computational model of visual attention for stereoscopic...
This paper investigates the problem of online active learning for training classification models from sequentially arriving data. This is more challenging than conventional online learning tasks since the learner not only needs to figure out how to effectively update the classifier but also needs to decide when is the best time to query the label of an incoming instance given limited label budget...
This paper introduces a simulation and modeling method for hydraulic systems, with a focus on system performance and fault analysis. In a first part, the concept and need for functional modeling are introduced. In a second part, this paper analyzes the difference between functional modeling and detailed modeling, and introduces the process of hierarchical simulation based on functional modeling. Finally,...
In this paper, we propose a computational model of visual attention for stereoscopic video. Low-level visual features including color, luminance, texture and depth are used to calculate feature contrast for spatial saliency of stereoscopic video frames. Besides, the proposed model adopts motion features to compute the temporal saliency. Here, we extract the relative planar and depth motion for temporal...
A new method of collaborative simulation of chemical reaction, fluid flow and heat transfer based on OpenFOAM is proposed. Then a case study of shell-and-tube reactor for a single shell and several reaction tubes pass reactor with a variable number of baffles and turbulent flow is performed. The results are observed to be sensitive to the turbulence model selection. The best turbulence model among...
Human can judge driver's driving ability by observing the vehicle motion in different traffic scenes. Identically, driving behavior can be the main basis for evaluating the performance of an unmanned vehicle in both field test and simulation test. Although simulation test avoids disadvantages of field test, existing simulation systems lack traffic scene data with perception granularity of visual sensors...
The traffic scenario consists of the road scenario and traffic elements. The original image sequences can be captured by a moving platform equipped with camera by driving along the road. In this paper, an approach based on augmented reality is proposed that supplements new elements (traffic cones, obstacles, etc.) into those image sequences. We model the traffic scenario in the 3D space of the scene,...
We demonstrate the influence of CW-seed's linewidth on the temporal coherence of the seeded supercontinuum, which enhances the contrast ratio of the interference fringe by ∼5 dB and ∼3 dB at four-wave mixing sidebands respectively.
The siphon bend of internal carotid artery (ICA) has been reported as the most preferred location for stenoses. The geometry of the siphon is considered to be associated with the atherosclerotic stenos is. In the present study, the shape of ICA was classified into 3 types with different curvature and planarity. Accordingly, 3 siphon models were experimentally studied with particle image velocimetry...
MD (Molecular Dynamics) simulation is widely used for biology and chemistry study and requires computing power several orders of magnitude beyond today's commonly available computing systems. While the heterogeneous multi-core system offers substantial computation power with both lower cost and lower power consumption, its unconventional hardware architecture poses significant challenges to programmers...
Clusters of Symmetric MultiProcessing (SMP) nodes with multi-core Chip-Multiprocessors (CMP), also known as SMP-CMP clusters, are becoming ubiquitous today. For Message Passing interface (MPI) programs, such clusters have a multi-layer hierarchical communication structure: the performance of intra-node communication is usually higher than that of inter-node communication; and the performance of intra-node...
