Abstract:
A method of identifying long shots of sports video comprising receiving a video frame comprising a plurality of pixels, classifying each of the plurality of pixels as a candidate field pixel or a candidate non-field pixel, determining whether at least a predefined percentage of the plurality of pixels are candidate field pixels, calculating a first standard deviation, the first standard deviation being the standard deviation of the hues of all candidate field pixels, and classifying the video frame as a long shot of sports video when at least the predefined percentage of the plurality of pixels are candidate field pixels and the first standard deviation is equal to or lower than a predefined maximum standard deviation value.
