Abstract :
This paper presents a robust method to detect scene changes from compressed video streams. Scene changes are detected with DC components of DCT coefficients in MPEG encoded video sequences. Instead of decoding full frames, partial macroblocks of each frame, horizontal and vertical macroblocks, are decoded to perform scene changes. This method detects abrupt and gradual scene changes by decoding minimal blocks and saves a lot of computations. The experiment results show at least 95% detection performance for dramas, news and animations
