The “What’s on HDtv?” blog is about video (and, occasionally, audio) in the HDTV age. This article is about 2K vs. 4K resolutions and which to choose.
Web assisted annotation, semantic indexing and search of television and radio news
The Rich News system, that can automatically annotate radio and television news with the aid of resources retrieved from the World Wide Web, is described. Automatic speech recognition gives a temporally precise but conceptually inaccurate annotation model. Information extraction from related web news sites gives the opposite: conceptual accuracy but no temporal data. Our approach combines the two for temporally …
Ritroverai- A web application for semantic indexing and hyperlinking of multimedia news
In this paper, a system, RitroveRAI, addressing the general problem of enriching a multimedia news stream with semantic metadata is presented. News metadata here are explicitly derived from transcribed sentences or implicitly expressed into a topical category automatically detected. The enrichment process is accomplished by searching the same news expressed by different agencies reachable over the Web.
Camera Motion Detection
Manual camera motion annotation has been performed by three groups using a tool provided by Joanneum Research. Some types of content made it difficult or impossible for human annotators to describe the camera motion. The comparison of annotations of the same content done by two groups shows significant differences for some features. We discuss the questions that arise from the …
Dirt detection for archive film restoration using an adaptive spatio-temporal approach
In this paper, an adaptive spatio-temporal approach for the detection of dirt in archive film sequences is proposed. By combining useful features from conventional stand-alone spatial and temporal approaches this method achieves better performance in terms of both correct dirt detection rate and false alarm rate.
Content augmentation for mixed-mode news broadcasts
Rich News, a system that augments news broadcasts with textual content, is described in this report. The system identifies individual stories in news broadcasts, and annotates them with related content from the World Wide Web.
