The Waisda? (which translates to What’s that?) video labeling game was launched in May 2009. It invites users to tag what they see and hear and receive points for a tag if it matches a tag that their opponent has entered. Waisda? is the world’s first operational video labelling game. The underlying assumption is that tags are most probably valid if there’s mutual agreement. Over 2,000 people played the project and within six months, over 340k tags have been added to over 600 items from the archive. Initial findings have been published earlier, when the pilot period was still running. This evaluation report (PDF download, in Dutch), includes a quantitative and qualitative analysis of the tags, as well as a usability study of the game environment and a study into the incentives that apply to people playing the game. The evaluation report is written by Lotte Belice Baltussen, in collaboration with Maarten Brinkerink and Johan Oomen of the Netherlands Institute for Sound and Vision R&D Department. Researchers at the VU University Amsterdam, Business Web & Media Section, also provided crucial input. The VU University Amsterdam carries out this research in light of their involvement in the PrestoPRIME European research project.
The evaluation report provides evidence that crowdsourcing video annotation in a serious, social game setting can indeed enhance retrieval of video in archives. It features success factors organizations need to take into account in setting up services that aim to actively engage their audiences online. The main conclusions are listed below:

Early December, the website www.hollandsglorieoppinkpop.nl was launched; an experimental video search engine offering an innovative way to browse through performances of the Pinkpop festival. Pinkpop, celebrating its 40th birthday this year, is the oldest annual festival in the world. The “Hollands Glorie op Pinkpop” website uses state-of-the-art multimedia retrieval technology, allowing visitors to access performances and interviews based on automatically detected visual concepts and audio transcripts. The website shows how multimedia retrieval technology can be used to easily navigate through collections of video.
“Hollands Glorie op Pinkpop” received financial support from the national research programme MultimediaN, technology foundation STW, and Images for the Future.
Technology developed by Dutch Universities
The technology behind the platform has been built over the past years by Dutch Universities, notably within the scope of the MultimediaN research programme. One of the main components is the MediaMill semantic video search engine. The search engine translates pixels to text; enabling the automatically detection and labeling of visual concepts in images, for instance ‘guitarist’ and ‘drummer’. The MediaMill system, developed by the University of Amsterdam, is considered to be amongst the best performing video search engines worldwide. The Pinkpop project is the first publicly accessible platform that demonstrates the use of this technology. Read the rest of this entry »

Video-fingerprinting systems detect whether a particular segment of video is (partly) based on the same original video as video footage in a database of reference videos. Typical applications the media domain include detection of copyright infringement, counting broadcasts of advertisements, detection of changes in advertisements and new applications are in development. One of these new applications is linking archive footage to finished television productions. For instance to show the link between a documentary and all the clips in the archive it consists of. This will allow users to browse through collections of video in a novel way, as currently the metadata is not supplying users with such detailed metadata.
Sound and Vision is involved in a project (vdFP) that will examine the possibilities of Video Fingerprinting for the abovementioned applications. The vdFP project is managed by TNO and JOANNEUM RESEARCH. Two industrial partners (ZiuZ and HS-ART Digital) and Sound and Vision complete the consortium. Recently, the project has released a State of the Art report. That can be downloaded here. Read the rest of this entry »

The annual conference of the Association of Moving Image Archivists is a vibrant and dynamic event that brings together archivists, academics and industry professionals. This year, St. Louis is the host city for the AMIA Conference. On the second day of the event, Johan Oomen (Netherlands Institute Sound and Vision) presented the Images for the Future project. The presentation focussed on on user generated video and user generated metadata. Open Images, the Waisda? tagging game, the Beeld and Geluid wiki and Video Active have been presented as example cases. The presentation is available online at Slideshare.
