ABSTRACT:
A method, in one exemplary embodiment, for automatically detecting scene changes within a digital video sequence including a succession of frames, including computing metrics, for each of a plurality of frames from a digital video sequence, the metric of a frame being a measure of distance between the frame and a given frame, identifying a candidate frame for which the metric of the candidate frame differs from the metric of the predecessor frame to the candidate frame, by at least a first threshold, determining whether the metrics of successive ones of each of a first plurality of frames, successively following the candidate frame, differ from one another by less than a second threshold, and further determining whether the metrics of each frame of a second plurality of frames, successively preceding the candidate frame, are larger than a third threshold. A system, of one exemplary embodiment, is also described and claimed.
