Monitoring near-duplicate videos over continuous video streams
Abstract:
Online video steam data is surging to an unprecedented level. Massive video publishing and sharing impose heavy demands on continuous video near-duplicate detection for many novel video applications. In this talk, we will present an accurate and accelerated system for video near-duplicate detection over continuous video streams. We propose to transform a high-dimensional video stream into a one-dimensional Video Distance Trajectory (VDT) to monitor the continuous visual changes of consecutive frames, based on which video similarity is derived. To avoid unnecessary sequence similarity computations, an efficient sequence skipping strategy is also applied. Extensive experimental results show the effectiveness of our proposals.
