A Web-based Tool for the Visual Analysis of Media Annotations

International audienceMultimedia annotation algorithms infer localized meta-data in multimedia content, e.g. speakers or appearing faces. There is a growing need of experts from this domain to perform advanced analyses, that go beyond medium-scale quality metrics. This paper describes a novel visual tool, that applies interactive visualization principles to the multimedia expert concerns. Multiple coordinated views, augmented by interactive inspection facilities, ease the navigation in media annotations, and the visual detection of relevant information. The effectiveness of the proposition is demonstrated by experimental scenarios on a real multimedia corpus
