US 5,521,841 A · Browsing contents of a given video sequence

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.

A computer-implemented 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 said sequence and/or to decide whether said contents of a video sequence are relevant to a user, said video sequence having been pre-processed to detect scene changes and to build Rframes, an Rframe being a representation of a sequence of images, and for allowing a user to scroll through said Rframes in a given manner and to stop at a selected Rframe for processing, said method comprising:

(a) playing said video sequence from the beginning of a shot represented by said selected Rframe to the end of said shot;
(b) detecting all Rframes having respective degrees of similarity to said Rframe selected by said user;
and
(c) presenting said similar Rframes to said user in a size or scale representative of said degrees of similarity.

(a) playing said video sequence from the beginning of a shot represented by said selected Rframe to the end of said shot;
(b) detecting all Rframes having respective degrees of similarity to said Rframe selected by said user;
and
(c) presenting Rframes having one of a predetermined degree of similarity to said Rframe selected by said user and predetermined degree of dissimilarity to said Rframe selected by said user.
