Abstract
A method for forming a video summary for a digital video having a time sequence of video frames, comprising using a processor to perform the steps of: determining a set of key video frames for the digital video; ranking the key video frames responsive to a predefined criterion; forming key video snippets corresponding to one or more highest-ranked key video frames according to a predefined set of criteria, including a criterion which specifies the total time duration for the video summary and a criterion which specifies the minimum time duration for each of the key video snippets; assembling the key video snippets to form a video summary; and storing a representation of the video summary in a processor-accessible memory.
