Abstract
A method for forming a video summary for a digital video sequence. The method includes capturing a digital video sequence with a digital video capture device, wherein the digital video sequence includes a plurality of video frames. At least one of the video frames in the digital video sequence is analyzed at the time the digital video sequence is captured to determine one or more feature values. The digital video sequence; is compressed and stored in a processor-accessible memory. The feature values are analyzed, without decompressing the stored compressed digital video sequence, to identify one or more key video snippets, each key video snippet corresponding to a set of video frames from the digital video sequence. The key video snippets are assembled to form a video summary which is stored in a processor-accessible memory.
