最邻近插值和双线性插值对所给图像进行缩小和放大操作。限制于位图操作。-The nearest neighbor interpolation and bilinear interpolation to the image, zoom in and out of operation. Limited bitmap operations, can not be used for other types of files. Remember! Do not like do not spray....

加权插值算法，包括加权最近邻插值，加权双线性插值，加权双三次插值，直接运行demo.m就可以。-Weighted interpolation algorithm, including weighted nearest neighbor interpolation, bilinear interpolation, weighted weighted double three interpolation, directly run the demo. M.
