这一章我们将介绍图象的几何变换，包括图象的平移、旋转、镜象变换、转置、放缩等。如果你熟悉矩阵运算，你将发现，实现这些变换是非常容易的。-This chapter we will introduce the image of the geometric transformations, including the image shift, rotation, mirror transform, transpose, zoom and so on. If you are familiar with matrix operations, you will find the implementation of these transformation is very easy.
