Perceptual image of a product plays a significant role in decision making when users choose a product whose basic function is homogeneous nowadays. Designers try to design products that meet the all kinds of demands of users. However, a big gap between designers and users exists owning to the subjectivity of designers' experience. An objective model to recognize perceptual image of products is proposed...
For applications in navigation and robotics, estimating the 3D pose of objects is as important as detection. Many approaches to pose estimation rely on detecting or tracking parts or keypoints [11, 21]. In this paper we build on a recent state-of-the-art convolutional network for slidingwindow detection [10] to provide detection and rough pose estimation in a single shot, without intermediate stages...
The most difficult challenge of converting the PSCAD model for use in the Electromagnetic Simulation Program (ESP), developed by China Southern Power Grid (CSG), is that the PSCAD model is graphically-based and the topology information of all elements is realized via the closeness of the coordinates of the element. This paper describes the details of PSCAD models, how to map the PSCAD model into the...
Pollution deposition of insulators may lead to flashover, and the factors affect it should be studied to better prevent the occurrence of pollution-induced flashover. In this paper, by taking XP-70 insulator as the sample, the software FLUENT was used to simulate the airflow field distribution as well as the particle collision coefficient (P) around insulator string. At the same time, a natural contamination...
Metallic enclosures effectively reduce electromagnetic interference in high intensity radiated field (HIRF) environments. However, any aperture - e.g. for wireless communication with the outside - will degrade the shielding. In this paper, apertures covered with diode grids are investigated for energy selective field protection. If properly designed, such apertures will effectively block the HIRF...
Fluid guiding methods could generate high-resolution simulation results from basic low-resolution simulation results, rather than direct simulation. However, because of dissipation, the high-resolution results always leads to huge shape differences from low-resolution inputs. Previous fluid guiding methods often use complex fluid control methods or artificial force to reduce shape differences. Such...
The cardiac dynamics simulation possesses the important research significance and the strong application value in bionic human organs manufacturing field. In this paper, we propose a particle-based model based on SPH (Smoothed Particle Hydrodynamics) which applies to cardiac rhythm simulation by combining with biomechanics, elasticity mechanics and topological knowledge. This model constrains the...
Images/videos of outdoor scenes are usually degraded by the turbid medium in the atmosphere. In this paper, a novel single image-based dehazing framework is proposed to remove haze effects from image/video, where we propose two novel image priors, called the pixel-based dark channel prior and the pixel-based bright channel prior. Based on the two priors with the haze imaging model, we propose to accurately...
A fused background model that combines the eigenbackground with Gaussian models is proposed. We adopt the eigenspace model to build the intensity information for each pixel. Unimodal Gaussian density methods with less computational cost are used to describe color information for each pixel. An adaptive strategy is used to integrate the two models. Using the fused background model, we subtract the...
Broadcast encryption schemes are suitable for one-way content distribution and protection applications.However, most of the related papers are from the theoretical point of view, and there is something useful for implementation being overlooked. In this paper, we introduce the pay-TV system as a concrete implementation of broadcast encryption schemes, and simulate the transmission performance of four...
High dimension and hard describing of cluster are the primary problems of clustering algorithm based on vector model. The conditional probability combined with rough set is introduced in this paper, and a information retrieval model based on fuzzy rough set is proposed, finally its document clustering algorithm is designed in detail. Especially the description and updating of cluster is studied in...
To deal with the traditional problem of N-player iterated prisoner's dilemma (NIPD), this paper proposes a classify-coding scheme of individual strategy, related to the thoughts of people in reality. The simulation experiments indicate that the NIPD model based on the new strategy features a dynamic, successive multi-phases equilibrium. A quantitative analysis on multi-phases equilibrium is made,...
