摘要
The video signal processor 10 includes a scene detector 16 which uses features extracted for visual segments and/or audio segments resulted from segmentation of an input stream of video data, and a criterion for measurement of similarity between visual and/or audio segment pairs, calculated for each of the features using the similarity measurement criterion, to detect two visual segments and/or audio segments whose time gap is within a predetermined temporal threshold and whose dissimilarity is less than a predetermined dissimilarity threshold and group the segments into a scene consisting of visual segments and/or audio segments reflecting the semantics of the video data content and temporally contiguous to each other.
