Embodiment Construction
[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0041] figure 1 Listed the schematic flow sheet of each step method of the present invention, comprises the following steps:
[0042] 1. Shot boundary detection
[0043] First, use the spatio-temporal slice algorithm (spatio-temporal slice) for shot boundary detection, and divide each news event in the news video library into shots. For a detailed description of the spatio-temporal slice algorithm, please refer to the document "Video Partitioning by Temporal Slice Coherency" [C.W. Ngo, T.C. Pong, and R.T. Chin, IEEE Transactions on Circuits and Systems for Video Technology, Vol.11, No.8, pp.941-953, August, 2001].
[0044] In addition to the spatio-temporal slicing algorithm used in the present invention, there are many methods for segmenting shots, for example, subtraction of adjacent frames, difference of histograms of adjacent fr...
