A method for detecting scene cuts and similar pictures in a video
sequence, including receiving pictures in a video sequence, extracting a
set of features from two temporally consecutive pictures, computing a sum
of square errors for the set of features with respect to the features of
the previous picture, determining whether the error exceeds a predefined
threshold and in response to the error exceeding the predefined
threshold, detecting a scene change, and determining whether the error is
less than a certain threshold thus detecting a similar picture has been
found.
