We propose a robust approach for aligning lecture slides with lecture videos using a combination of Hough transform, optical flow and Gabor analysis. A Markov decision process model is used to incorporate prior knowledge for enhanced recognition. We demonstrate synchronization of slides with videos containing de-focused slide content, speaker occlusion as well as camera pan, tilt and zoom sequences. Experimental results confirm the effectiveness of our approach for multimedia indexing applications. |
