Computational video is the study and application of the processing of streamed video data. This field of research is emerging from the convergence of two technologies:

Digital cameras. Over the past few years, consumer digital cameras have increased in popularity, and digital video cameras will soon follow. At the same time, several emerging applications, such as traffic monitoring and security systems, have increased the public's tolerance of video surveillance of public spaces. This trend towards ubiquitous video will continue as new and useful applications are developed.
High performance computing and high bandwidth networks. Increases in network bandwidth and computing power are also significant, since they mean that the capability to transmit and process video data in real-time is readily available.

In addition, past and current research in machine vision has provided some practical solutions to some of the fundamental processing problems inherent in processing video. For example, from a video sequence it is possible to find the camera path, to find faces and people, to interact hands-free with a computer and to make simple 3d models.

Finding innovative ways to process digital video and digital images will lead to new and useful technologies in a variety of application areas and will support the trend to ubiquitous video. As such, the Group's staff conducts fundamental research in the computational video field, in order to produce the basic capabilities that are necessary to develop these new technologies.

The Group's research is currently targeting the following application areas:

stereo processing from off-the-shelf cameras
recognition and tracking from video
reconstruction from multiple cameras
vision-based user interfaces
augmented reality
broadband visual communications
advanced video-conferencing
beamed microphone arrays

Key Capabilities

video and image processing
geometric signal processing
pattern recognition
