Abstract:
　

Video search has become a compelling research topic in recent years, due to the proliferation of online video uploading/sharing sites and the exponential explosion of video data. In this demonstration, we showcase a Web-based integrated platform, UQLIPS, which performs online detection of near-duplicate occurrences over continuous video
streams, as well as retrieval of near-duplicate clips from segmented video collections. Our method to detect relevant sub-sequences in a streaming video is characterized by a novel one-dimensional distance trajectory capturing the changes of consecutive frames. Such a
trajectory is further represented by a sequence of compact signatures. An effective similarity measure is devised to compare the trajectory with multiple query videos.
