We present a fully automatic system for extracting the semantic structure of a typical academic presentation video, which captures the whole presentation stage with abundant camera motions such as panning, tilting, and zooming. Our system automatically detects and tracks both the projection screen and the presenter whenever they are visible in the video. By analyzing the image content of the tracked...
In this paper, we present a saliency-aware image completion method which takes full advantage of a saliency detection result. On one hand, the saliency map is incorporated into the completion order computation procedure to take human visual attention into account. On the other hand, the saliency map used in patch matching makes the searched result more accurate and smooth. Furthermore, we employ an...
In this paper, we propose a geometric algorithm for interpolating a given polygon using non-uniform cubic Bsplines. Geometric interpolation uses the given polygon as the initial shape of the control polygon of the B-spline and reduces the approximate error by iteratively updating the control points with the deviations from the corresponding interpolated vertices to their nearest foot points on the...
This paper proposes multigoal implementations of the Dijkstra's shortest path algorithm and the boundary iterative-deepening depth-first search (BIDDFS). The algorithms were modified to allow for the search of more than one goal in a single expansion pass. The aim of this is to reduce the operational redundancy and hence the time taken for calculating multiple start-goal node pairs. Simulations using...
With the information technology and the communication rapid development, information resource digitization has become the reality. The Personalized information service is important tendency of the development of digital library, which is the key that it can attract user to participate in the build of digital library. This article carries thorough in-depth analysis to the construction of My Library...
As spectral clustering has the advantage of recognizing non-convex distribution, it has been widely used in image segmentation and other areas. However, when the spectral clustering algorithm deals with large size images, in order to get the affinity matrix, it costs a lot of computation time, so its applications are limited. To solve this problem, this paper proposes a fast image segmentation algorithm...
This paper describes a management platform for a web client side of internet-based electrical engineering lab using SSH framework. This experiment platform covers 6 subjects, dividing users into 6 levels of authority to manage. Because of the excellent scalability, the management platform can be developed into an integrative system with combination of virtual and physical experiment.
A novel traffic indication symbol detection and recognition method is introduced in this paper. We firstly apply color detection and shape detection on the real-time image to locate and extract the symbol region. Then the traffic indication sign is matched and recognized by using shape context. Experimental result demonstrates the proposed algorithm has good performance on recognition and more robustness...
By means of single-factor experiment method, Fenton-like reagent was applied to treat molasses alcohol wastewater. The results showed that optimal processing parameters are, the initial pH=6.0, FeCl3·6H2O for 1000g/m3, 3%H2O2 for 6.7L/m3, stirring time for 5min. At the optimal condition, color and CODCr removal rates are 92.76% and 75.53%.
Workflow technology is a key technology which is used for modern organization to achieve process management and process control, which has provides effective support for the process modeling of higher graduate education and the overall management. In this paper, workflow concept is introduced firstly, and then based on the workflow reference model, the workflow engine technology and statistical reporting...
Industrial cluster is emerging as a way of stimulating the development of economic all over the world, which is the focus in both theory and practice currently. Furthermore innovation plays a vital role in keeping sustained competitiveness of industrial cluster. In order to describe and assess the essence and rule of innovation ability within industrial clusters, a system is modeled in this paper...
