Video Retrieval Based on Words-of-Interest Selection
[chapter]
2011
Lecture Notes in Computer Science
Preserved Fulltext
In this paper, we present a content based video retrieval technique based on selected Words-of-Interest (WoI) that utilizes visual words spatial proximity constraint identified from the query. ...
One of the state-of-art approaches is the Bag-of-visual Words (BoW) based technique, where images are described by a set of local features mapped to a discrete set of visual words. ...
Introduction The rapid growth of video resources available on the internet requires effective content based video retrieval technology. ...

In this paper, we propose a novel technique to enhance BoW by the selection of Word-of-Interest (WoI) that utilizes the quantified temporal motion coherence of the visual words between the adjacent frames ...
The "Bag of Visual Words" (BoW) framework has been widely used in query-by-example video retrieval to model the visual content by a set of quantized local feature descriptors. ...
In context of queryby-example video retrieval, we believe that some selected visual words, called Words-of-Interest (WoI), are more related to the user's interest than others. ...

In this paper, we focus on the following features: (1) combine recognized video contents (at higher level and output from a video analysis module) with visual words (at low level computed over all the ...
raw video frames) to enrich the video indexation in a complimentary way; using this scheme user can make queries about objects of interest even when the video analysis output is not available; (2) support ...
We have presented in section 5 separate results of two indexing approach aspects (one is based on the recognized video content and the other is based on the visual words). ...

This paper presents a key frame based method that employs shot boundary detection and "bag-ofvisual-words (BoW)" based on local keypoints for key frame extraction and semantic concept detection. ...
Finally, this paper performs a query by concept search for video retrieval. The experimental results demonstrate that the proposed approach is capable of retrieving videos. ...

In case of inquiry and retrieval, such a video retrieval method as combines key word and key frame is applied. ...
Now, a teaching video retrieval system based on key frame has been designed and achieved. The system uses mutual information extraction for the video key frame extraction. ...
The retrieval based on key word or text uses precise matching of key word or text; the retrieval based on key frame relies on computing and inquiring the similarity matching in terms of visual feature ...
