LIT: search engine for video transcriptions with media streaming

ACM Multimedia 2009 – Sirio

In this technical demonstration we show a web video search engine based on ontologies, the Sirio system, that has been developed within the EU VidiVideo project. The goal of the system is to provide a search engine for videos for both technical and non-technical users. In fact, the system has different interfaces that permit different query modalities: free-text, natural language, graphical composition of con- cepts using boolean and temporal relations and query by visual example. In addition, the ontology structure is ex- ploited to encode semantic relations between concepts per- mitting, for example, to expand queries to synonyms and concept specializations.

ACM Multimedia 2009 – Arneb

In this technical demonstration we show the current version of Arneb, a web-based system for manual annotation of videos, developed within the EU VidiVideo project. This tool has been developed with the aim of creating ground truth annotations, that can be used for training and evalu- ating automatic video annotation systems. Annotations can be exported to MPEG-7 and OWL ontologies. The system has been developed according to the Rich Internet Applica- tion paradigm, allowing collaborative web-based annotation.

Shawbak project: an interactive surface for museums and exhibitions

EVA 2009 – Natural Interaction

This paper presents the media interaction systems implemented at the Mont'Alfonso Fortress, close to Castelnuovo Garfagnana (Lucca). The stronghold was built at the end of the 16th century and after being abandoned for decades it was recently submitted to a complete restoration. A multimedia environment, made of large projections, was developed in one of the buildings inside the fortress. Users can interact with natural body gestures: the multimedia contents of two tables are driven by user's hands, while projections on walls and floor are activated by motion detection. All the sensing is made using near-IR cameras.
