python智能图片识别系统（图片切割、图片识别、区别标识）

技术介绍

你好！ python flask图片识别系统使用到的技术有：图片背景切割、图片格式转换（pdf转png）、图片模板匹配、图片区别标识。

运行效果

第一组：

图片1：

图片2：

开始上传：

上传成功、图片预览：
（emmm…抱歉图片大小未处理，有点大哈）

识别效果：

成功了。。。

第二组：

这会搞个复杂些的，也是实用的图片

图片1：（图片仅供交流，侵权删）

图片2：

你会发现，其实图片2是图片1的子图，这下我们看看程序处理的效果：

还可以哈，截取了图片1中的匹配部分，然后标识出来了区别

关键代码

写在最后

写这个功能的代码是费了很大劲的，路过的朋友点个赞哈。
需要源码的，可以Q我交流：3459067873
