Abstract

Video-skimming for the purpose of reducing the view time of video sequences is an important multimedia application. By chaining key isolated frames together, one can obtain a short synopsis of the video. In this paper we will demonstrate image characterization techniques based on a new method for calculating the optical flow in a video sequence. It is shown that a nonlinear anti-diffusive correction allows for a better characterization of camera and subject motion within a scene.
