In this paper, we propose an interactive method to generate dynamic video synopsis by integrating both content and context information. First, the methods for content and context information mining are presented. Then, we construct a network with both cues for video shots correlation. Moreover, the mechanism for dynamic video synopsis generation with three different strategies is presented. Based...
Java Code Hierarchical Visualization Tool (JCHVT) is a software visualization system oriented to Java source code, which has been designed on the concept of service and with reference to Class diagram and Polymetric view. JCHVT is able to automatically create a hierarchical view of the software system, which can reflect the relationships among classes, structure of the system and even the roles of...
