bilinear interpolation algorithm

基本解释

The bilinear interpolation algorithm is used to correct the distorted QR code and then repair the image with morphology.
然后通过双线性插值算法对发生倾斜的QR码进行纠正，并对结果修补。

Interpolation on gray images is needed in the course of geometric operation. Bilinear interpolation algorithm is effective, but its program is complex and the running time is longer.
几何运算要求对图像进行灰度值插值，双线性算法可产生令人满意的效果，但是程序较复杂，运行时间较长。
