code for approximate nearest neighbor algorithm,最经典的近似搜索算法-code for approximate nearest neighbor algorithm

本算法采用C#进行界面编程，实现图像的放大缩小和旋转，可自选放大缩小倍数和旋转角度，也可以自行选择插值方式：最近邻插值、双线性插值和双三次插值-The algorithm uses C# for interface programming, image zooming and rotation can be optional zoom factor and the rotation angle can also choose their own interpolation method: nea
