This article mainly introduces the relevant knowledge of how C # verifies the similarity of two QQ avatars, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe you will gain something after reading this article on how to verify the similarity of two QQ avatars. Let's take a look.

Use c # to find out the similarity between the avatar of some other qq and your own, and first look at the effect picture.

Here I use the avatar on the left as the basic picture of the comparison. What I am doing now is to compare one picture to one, because it is not difficult to understand one to one, one to many, and we can get similar pixels. Then the percentage greater than that is the change of the same picture. Here is the complete code.
