文档包括双线性插值算法和最近邻域算法的详细介绍，以及算法的相关计算。-Documentation includes bilinear interpolation algorithm and the nearest neighbor algorithm which is described in detail, as well as algorithms related calculations.

此代码主要是利用最邻近差值法，双线性插值法，高阶插值法实现图像的旋转以及缩放-This code is the difference between the use of the nearest neighbor method to achieve image rotation bilinear interpolation, higher-order interpolation and scaling

最近邻插值法nearest_neighbor是最简单的灰度值插值。也称作零阶插值，就是令变换后像素的灰度值等于距它最近的输入像素的灰度值。(Nearest neighbor interpolation method, nearest_neighbor is the simplest gray value interpolation. Also called zero order interpolation, that is, the gray value of the transformed p
