图象的插值缩放

图象的插值旋转

图象的剪切

在图象的几种几何操作中，图象的缩放和旋转都要用到插值操作。插值算法的好坏直接关系到图象的失真程度，插值函数的设计是插值算法的核心问题。因此，在具体介绍这几种几何操作前，有必要先介绍一下插值的基本原理。

-image interpolation zoom image interpolation rotary shear image in the image of several geometric operation, image scaling and rotation should be used interpolation operation. Interpolation algorithm directly related to the distortion of images, interpolation function interpolation algorithm design is the core of the problem. Therefore, the specific details of these types of geometric pre-operational, it is necessary to first explain the basic tenets of interpolation.
