由于摄像机的运动，我们通常不能准确估计物体的运动，利用运动补偿，得到视频中重要物体的运动。-As a result of camera movement, we usually can not be an accurate estimate of the movement of objects, using motion compensation, to be the most important video of the movement of objects.

二维DCT编码，实现图像的运动估计，较好的完成估计任务。-Two-dimensional DCT coding for image motion estimation, a better estimate to complete the task.
