US 2002/0175932 A1 · Method for summarizing news video stream using synthetic key frame based upon video text

Abstract

The present invention relates to a method for summarizing a news video stream using a synthetic key frame based upon news video text. The method according to the invention generates the synthetic key frame by allocating different importance measures according to an icon text region and a general text region. In the method according to the invention, the highest importance measure is allocated to the icon text region extracted from a news video stream, different importance measures are allocated to general text according to weights, a certain number of general texts are selected, and the synthetic key frame is generated by synthesizing the icon text region and the selected general text regions
