推荐答案

将存储的图像与Thumbscanner中的图像进行匹配是不好的！您将永远不会获得完全相同的图像.
我对指纹算法一无所知，但是我敢肯定，它比实现确定两个图像的相似度的算法更容易实现和理解.

Matching a stored image to an image from a thumbscanner is bad! You''ll never ever get the exact same image.
I know nothing about fingerprint algorithms but I''m sure it''s easier to implement and understand than an algorithm that determines how similar two images look like.
