我们提出了一种从HDV摄像机记录的高分辨率图像中生成动态讲座视频的方法。课程图像被裁剪，以跟踪讲师所在的区域。该方法利用双边滤波来避免因时间差异引起的抖动运动，生成基于广播员拍摄技术的伪摄像机运动(平移)。我们对我们的方法进行了评估，并通过主观实验验证了算法的有效性。
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.
