It is our pleasure to welcome you to the second TRECVid Video Summarization Workshop, held inconjunction with ACM Multimedia 2008. TRECVid itself is a series of evaluation workshops held each November going back to 2001, in which systems are benchmarked on various video processing tasks in an open, metrics-based forum. Tasks have included search, high-level feature extraction, shot and story boundary determination, copy detection, surveillance event detection, --- and this year, a second take on summarization of BBC rushes video, held separately as this ACM Multimedia workshop.
Thirty-one research groups from around the world developed video summarization systems to be tested against 40 rushes videos provided by the BBC Archive. Rushes video is the highly redundant, unedited, raw material from which finished productions are made and represents a largely unused potential source of reusable video material. But how to find out efficiently what material a rushes video contains? Summarization may be part of the solution. The system task was to take each video and automatically compress out redundant and insignificant material to create a summary with duration at most 2% of the original video. Ground truth lists of important segments were created by humans watching the full videos. Each summary was then judged by three humans with respect to how much of the ground truth was included and how well-formed the summary was. The program committee accepted an overview paper and 26 papers from individual participating research groups describing their detailed results and technical approaches, each paper having been reviewed anonymously by 3 reviewers.
This paper describes an evaluation of automatic video summarization systems run on rushes from several BBC dramatic series. It was carried out under the auspices of the TREC Video Retrieval Evaluation (TRECVid) as a followup to the 2007 video ...
Video summarization is essential for the user to understand the main theme of video sequences in a short period, especially when the volume of the video is huge and the content is highly redundant. In this paper, we present a video summarization system, ...
In this paper, our techniques used in TRECVID'08 on BBC rush summarization are described. Firstly, rush videos are hierarchical modeled using formal language description. Then, shot detection and V-unit determination are applied for video structuring; ...
This paper describes the video summarization system built for the TRECVID 2008 evaluation by the Brno team. Motivations for the system design and its overall structure are described followed by more detailed description of the critical parts of the ...
Michael G. Christel, This paper discusses in detail our approaches for producing the video summaries submitted to the TRECVID 2008 BBC rushes summarization task, including the baseline method. Empirical work produced during and after the TRECVID 2007 rushes summarization ...
In this paper, the method used for Rushes Summarization task by the COST 292 consortium is reported. The approach proposed this year differs significantly from the one proposed in the previous years because of the introduction of new processing steps, ...
We describe the video summarisation systems submitted by Dublin City University to the TRECVid 2008 BBC Rushes Summarisation task. We introduce a new approach to redundant video summarisation based on principal component analysis and linear discriminant ...
This paper presents our approach to select relevant sequences from raw videos in order to generate summaries to Trecvid 2008 BBC Rush Task. Our system is composed of two major steps: First, the system detects "semantic" shot boundaries and keeps only ...
In this paper, we describe our approach to the TRECVID 2008 BBC Rushes Summarization task. First, we remove junk frames and dynamically accelerate videos according to their motion activity to maximize the content per time unit. Then, we search identical ...
In this paper we describe methods for video summarization in the context of the TRECVID 2008 BBC Rushes Summarization task. Color, motion, and audio features are used to segment, filter, and cluster the video. We experiment with varying the segment ...
The rushes is a collection of raw material videos. There are various redundancies, such as rainbow screen, clipboard shot, white/black view, and unnecessary re-take. This paper develops a set of solutions to remove these video redundancies as well as an ...
This paper describes the work performed by the GMRV-URJC team as part of the TRECVid 2008 Rushes Summarization benchmark. The main goal of our approach is to obtain good results by only using low-level techniques. Using only this kind of features also ...
In this paper we describe a system for video rushes summarization. The basic problems of rushes videos are three. First, the presence of useless frames such as colorbars, monochrome frames and frames containing clapboards. Second, the repetition of ...
Georges Quénot, In this paper, we present the first participation of a consortium of French laboratories, IRIM, to the TRECVID 2008 BBC Rushes Summarization task. Our approach resorts to video skimming. We propose two methods to reduce redundancy, as rushes include ...
We compare two methods for selecting segments to be included in a video skim, using lists of relevant as well as redundant segments created from different visual features as input. One approach is rule-based, and creates a weighted sum of the input ...
This paper describes the video summarization system developed by the partners of the K-Space European Network of Excellence for the TRECVID 2008 BBC rushes summarization evaluation. We propose an original method based on individual content segmentation ...
This paper describes the details of NHK's approach to the rushes summarization task in TRECVID 2008. From a broadcaster's point of view, removing redundancy and attaining a pleasant tempo/rhythm, as well as the recall ratio, are important. Here, we ...
Generating short summary videos for rushes is a challenging task due to the difficulty in eliminating redundancy and determining the important objects and events to be placed in the summary. Redundancy elimination is difficult since repetitive segments, ...
In this paper, we describe our system used to summarize BBC rushes, the TRECVID database. Our summarization process starts with shot boundary detection. Then we filter obtained shots to retain only useful ones. After that we try to localize from every ...
As the amount of recorded video data continually increases, a lot of teams around the world work to propose original methods on automatic video summarization. A particular kind of video is a rush: a rough draft of a movie or a documentary. In this paper,...
This paper describes our system and methodologies for the BBC rushes video summarization task of TRECVID 2008. The procedure of the system is composed of three major steps: shot detection, irrelevant and repetitive subshot removal, and final summary ...
This paper presents an efficient video summarization technique with the focus of generating video summaries that are pleasant to watch. The validity of the technique was tested in the TRECVID 2008 evaluation event. The results show the effectiveness of ...
