Abstract
A method for representing contents of a video sequence for allowing a user to rapidly view a video sequence in order to find a particular desired point within the sequence and/or to decide whether the contents of a video sequence are relevant to a user, the video sequence having been pre-processed to detect scene changes and to build Rframes, and for allowing a user to scroll through the Rframes and to stop at a selected Rframe for processing, comprises playing the video sequence from a point of the selected Rframe, detecting all Rframes having respective degrees of similarity to the Rframe selected by the user, and presenting the similar Rframes to the user in a size or scale representative of the degrees of similarity.
