1. A computer-readable medium having computer-executable instructions for discovering blurry frames of a digital video, comprising: inputting a frame from the digital video; computing a Laplacian energy of the frame and neighboring frames surrounding the frame; examining the Laplacian energy for the frame and the neighboring frames to determine whether the frame has an abrupt low energy value; and designating the frame as blurry if the frame has an abrupt low energy value as compared to the neighboring frames.
