Compact video signatures for near-duplicate detection on mobile devices

In this paper, we focus on generating compact but efficient video signatures on mobile devices so that users quickly know whether there are near-duplicates in the social network systems when they upload a video. For this, the proposed method employs the idea of inverted index that is one of the most popular text retrieval methods. Experimental results show that our method can achieve similar results compared with state-of-the-art method whereas it requires low memory and computation cost.
