Abstract
A method of determining a spatio-temporal feature value for frames of a sequence of video. A first frame and second frame from the sequence of video are received. Spatial feature values in each of the first and second frames are determined according to a plurality of spatial feature functions. For each of the spatial feature functions, a change in the spatial feature values between the first and second frames is determined. The spatio-temporal feature value is determined by combining the determined change in spatial feature values for each of the spatial feature functions.
