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.)
