Abstract: | Online video stream data are surging to an unprecedented level. Massive video publishing and sharing impose heavy demands
on continuous video near-duplicate detection for many novel video applications. This paper presents 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 Trend Stream (VTS) to monitor the continuous luminance changes of consecutive frames,
based on which video similarity is derived. In order to do fast comparison and effective early pruning, a compact auxiliary
signature named CutSig is proposed to approximate the video structure. CutSig explores cut distribution feature of the video
structure and contributes to filter candidates quickly. To scan along a video stream in a rapid way, shot cuts with local
maximum AI (average information value) in a query video are used as reference cuts, and a skipping approach based on reference
cut alignment is embedded for efficient acceleration. Extensive experimental results on detecting diverse near-duplicates
in real video streams show the effectiveness and efficiency of our method. |
