Description: 本文主要叙述的是利用MATLAB软件实现图像的几何操作。利用imresize() imrotate() imcrop() 等函数实现图像的缩放，选转，剪切。
在对图像的几种几何操作中，图像的缩放和旋转都要用到插值操作。-This paper describes the use of MATLAB software images of geometric operations. Use imresize () imrotate () imcrop () Function Image Scaling , elected to the shear. In the image of several geometric operation, image scaling and rotation should be used interpolation operation.

Description: 实现自己的imresize函数，具有最近邻和双线性两种操作方式-1. Write your own imresize() function code to simulate the matab function imresize(). You should implement at least the ‘nearest’ and the ‘bilinear’ methods.
2. Compare you result with the matlab function imresize(). You can use the two attached images or other images for testing.
