Abstract
The invention provides a method and apparatus for detecting a scene transition in digitized video data. The method includes determining if a gradual transition is detected in the video data that ends with a current frame based at least on the current frame and one or more previous frames in the digitized video data. The gradual transition has a length. The method includes comparing the gradual transition to a synthetically produced gradual transition spanning a same length and generated from starting and ending frames associated with the detected gradual transition and marking the detected gradual transition only if the detected gradual transition is sufficiently similar to the synthetically produced gradual transition.
