Abstract
A method for determining key video frames for a digital video having a time sequence of video frames, comprising using a processor to perform the steps of: analyzing the digital video to determine an importance value as a function of time; forming a warped time representation by temporal relocation of the video frames responsive to the importance value as a function of time; subdividing the warped time digital video sequence representation into a set of equal intervals; selecting a key video frame for each interval by analyzing the video frames within each interval; and storing an indication of the key video frames in a processor-accessible memory.
