Video surveillance is a key tool for enabling security personnel to monitor complex and dangerous environments, and the access to the semantic content of surveillance video has become a challenging research area. In this paper we present a query-processing system for investigating human activities in surveillance videos. The interaction between the user and the system happens through a gesture-based dialogue, which implements a novel question-answering model to support users during the information-seeking process. We also present a visual interface devised to facilitate the query-specification process.

Abstract
Video surveillance is a key tool for enabling security personnel to monitor complex and dangerous environments, and the access to the semantic content of surveillance video has become a challenging research area. In this paper we present a query-processing system for investigating human activities in surveillance videos. The interaction between the user and the system happens through a gesture-based dialogue, which implements a novel question-answering model to support users during the information-seeking process. We also present a visual interface devised to facilitate the query-specification process.File in questo prodotto:
