图象处理中经常用到图象抽取和插值，本程序就是常用的双线性插值法的实现-image processing frequently used images collected and interpolation, the procedure is commonly used by the bilinear interpolation to achieve

matlab环境下，使用双线性插值法实现缩放图像-matlab environment, using a bilinear interpolation method to achieve image zoom

插值法处理图像包含最近邻，双线性，双三次插值法处理图像-Interpolation processing image contains nearest neighbor, bilinear, bi-cubic interpolation image processing
