摘　　要：随着数字视频技术的发展,数字图像处理广泛应用于几乎所有与成像有关的领域。本文先讨论用简单变换实现图像旋转的过程和代价,并指出通过矩阵分解可以将二维旋转运算简化为三次一维的平移运算,最后给出3D空间中使用四元数替换矩阵的可能性和优越性。With the development of video technology, the digital, image processing is widely applied to almost all domains related to the formation of image. This paper first discusses how to use the simple transformation to realize the process of image rotation and gives its cost, then points out that the rotation of 2D image can be realized with three translation operations through decomposing matrix, and finally gives the possibility and superiority for using quaternions to substitute matrix in 3D space.
