The increasing online content has influenced users’ buying behavior. It has triggered a paradigm shift in marketing strategies, as the consumer is no longer swayed by marketers, instead relying on user comments for a particular product or service. This paper focuses on extracting information from feedbacks like suggestions and recommendation by the users that is often present along with the sen...

This paper describes our new multiple-camera architecture for real-time video analysis. This architecture uses an array of relatively inexpensive cameras to gather images in order to provide high resolution at low cost. The system also uses a hierarchy of cameras, including both wide-angle and telephoto views. Wide-angle cameras are responsible for camera coordination while telephoto cameras ar...

We present an automatic feature extraction procedure for the analysis of time-lapse light microscopy wound healing videos, which are used to record the closure of in vitro wounds made in confluent monolayers of cultured epithelial cells under a variety of experimental conditions. Because of the size and complexity of the moving image data type, and hence the length of time required to undertake...

The "Caméra Musicale" is an interface which allows a musical practice based on the movement of hands and fingers under a camera. Born from technologies and methods developed in the early eighties to create music from choreographic movements, the “Camera Musicale” has evolved during the nineties to become a user friendly device since 2003. This article describes its fundamental principles of ope...

Understanding the representations of 3D scenes as encoded in multiple views taken by a camera from different vantage points is central to many tasks in image and video analysis. These tasks range from recovering the camera motion, 3D structure of the scene and detection and characterization of multiple motions in video. We will demonstrate that the natural representations of a 3D scene in 2D im...

This work constitutes the first attempt to extract an important narrative structure, the 3-Act story telling paradigm, in film. This narrative structure is prevalent in the domain of film as it forms the foundation and framework in which the film can be made to function as an effective tool for story telling, and its extraction is a vital step in automatic content management for film data. A no...
