An Efficient Video Copy Detection Method Combining Vocabulary Tree and Inverted File

چکیده
In this paper, we present an efficient content-based video copy detection method based on vocabulary tree and inverted files. The copy detection system exploits complementary local features and video sequence matching. Using two different local features, vocabulary trees and inverted files are built respectively to get keyframes matching result. Histogram-based and diagonal-based sequence matching approaches are applied to detect the copy video sequences. The experimental results on the TRECVID 2011 video copy detection dataset show that the proposed system is effective and efficient.

Inverted File Based Search Technique for Video Copy Retrieval
A video copy detection system is a content-based search engine focusing on Spatio-temporal features. It aims to find whether a query video segment is a copy of video from the video database or not based on the signature of the video. It is hard to find whether a video is a copied video or a similar video since the features of the content are very similar from one video to the other. The main fo...

Abstract: This article presents an approach to object retrieval that searches for and localizes all the occurrences of an object in a video database, given a query image of the object. Our proposal is based on text-retrieval methods in which video key frames are represented by a dense set of viewpoint invariant region descriptors that enable recognition to proceed successfully despite changes i...
متن کاملSmall Vocabulary with Saliency Matching for Video Copy Detection
The importance of copy detection has led to a substantial amount of research in recent years, among which Bag of visual Words (BoW) plays an important role due to its ability to effectively handling occlusion and some minor transformations. One crucial issue in BoW approaches is the size of vocabulary. BoW descriptors under a small vocabulary can be both robust and efficient, while keeping high...
