利用近邻法的弱点实现图片缩小后变成另一张图

Overview

这是我一个视频的配套代码。 视频是:利用近邻法的弱点实现图片缩小后变成另一张图 https://www.bilibili.com/video/BV1Lf4y1r7dZ

配套代码中,仅generate.py是核心文件,其余的图片神马的,都是赠品。 这个核心文件利用了近邻法缩放的弱点,可以将图a的像素按顺序嵌入到图b中,然后生成图c。图c看起来和图b是基本一样的。不过,在PS软件或者python的PIL模块中使用近邻法把图c缩小到图a的尺寸时,图a就显示出来了。算是一种形式的“幻影坦克”吧。

使用方法: 假设generate.py、图a、图b都在同一目录下,且图a、图b均为png格式。 python generate.py 图a 图b 图c 回车后生成图c。
