We propose a method for generating a dynamic lecture video from the high resolution images recorded by a HDV camcorder. The lecture images are cropped to track the region of the instructor. Our approach uses bilateral filtering to avoid jittery motion caused by temporal differencing, and pseudo camera motion (panning) based on shooting technique of broadcast cameraman is generated. We evaluated our method, and showed that the effectiveness of our algorithm was verified through subjective experiments.
