Rapidly growing mobile and online videos have enriched our digital lives. They also create great challenges to our computing and networking technologies, ranging from video indexing, analysis, retrieval, to synthesis. We found that a significant gap still remains between low-level features and high-level semantics. The objective of this Workshop is to explore the state-of-the-art of video analytics and future directions. We intend to bring researchers from a broad range of backgrounds to discover computational theories and models behind the real-world video applications. We especially want to explore novel approaches toward semantic video understanding. These invited presentations include video search, video biometrics, video summarization, video forensics, three-dimensional face recognition, general saccadic motion, and tracking and cropping in video processing.
