用matlab编写逆投影变换程序，三个m文件分别代表最近邻插值法，双线性插值法，立方卷积插值法，通俗易懂，含有测试图片，打开就能用-Inverse projection transformation program, matlab prepared three m documents represent the nearest neighbor interpolation, the bilinear interpolation and cubic convolution interpolatio

图像缩放中最常用的双线性插值算法，效果很好-The most commonly used image scaling bilinear interpolation algorithm works well

This is the inverse of ImToPolar. imP is the polar image with M rows and N columns of data (double data between 0 and 1). M is the number of samples along the radius from rMin to rMax (which are between 0 and 1 and rMax > rMin). Mr and Nr are t
