Search-Based Content Analysis System on Online Collaborative Platform for Film Production

摘要

This paper uses retrieval technology to create a video content analysis system for collaborative film production. Present film production handles all contents as digital files and demands the collaboration of remote locations. This process requires contents transfer among locations and also collaboration tools like comment-based communication. For more creative collaboration, automatic content analysis that supports editing is very effective. We propose an online collaborative platform based on retrieval technologies for film production. Our system bases automatic content analysis on content retrieval techniques for both video and audio clips. A GUI-based interface connects this function to the online collaborative system, and the total system enables efficient and secure collaboration among remote locations. In particular, our search function yields more precise detection through accurate timing, system scalability, and memory savings. Experiments on real film materials show that our search function has enough retrieval accuracy to ease the editing tasks in film production.
