Abstract

Over the last couple of decades, more and more presentations are done on computer screen. The need to store or broadcast such presentation efficiently is in high demand across different application areas. This paper proposes a screen capture representation called vector quantisation. This system captures sequence of actions on a computer screen and minimizes its video file size for storage. It also minimizes bandwidth requirement if used for teleconferencing.
