Abstract:
1. A video processing method for detecting significant events from a video program comprising the steps of: computing short-time sub-band energies in an audio of the video program for plural audio sub-bands; detecting scene boundaries from the audio of the video program by detecting whether the short-time sub-band energies are less than a predetermined first energy threshold for longer than a predetermined first energy time interval; segmenting the video program into a plurality of scenes using the detected scene boundaries as boundaries; removing scenes from the video program having a length shorter than a first segment time interval; following said step of removing scenes detecting second scene boundaries in the audio of the video program by detecting further segmenting the video program into a plurality of scenes using the detected second scene boundaries as boundaries; further removing scenes from the video program having a length shorter than a predetermined second segment time interval; and classifying and ranking remaining scenes based upon short-time sub-band energy in the audio from largest to smallest.
