An Interactive Video Browsing With VINAS System

Following the technological advances carried out recently, there was an explosion in the number of available videos and their accessibility. This was largely justified by the fall of the acquisition prices of the memory supports and the increase their capacity, which facilitated the storage of a large number of video document databases in the computer systems. To make the exploitation of these collections effective, it is necessary to install tools that facilitate access and handle them. In this paper, we propose a new approach for semantic browsing in a large video collection. Our approach is based, essentially, on a structuring of the video concepts. Indeed, a weight is calculated to measure the membership degree of a concept at different levels (context / concept / video). We developed the Video Navigation System (VINAS) to test our approach. A visual metaphor inspired by tag cloud concept is also set up in our VINAS system to help with the comprehensive semantic video browsing. A user study made on our VINAS system showed that the proposed approach can help the user with the semantic browsing in video collection.
