I don’t know if the imagick extension in php can achieve what you said. Please refer to the documentation and take a look at imagick

This is difficult to judge.

But there is an idea, because the pictures generated by the Gaussian blur algorithm will have certain characteristics in the data (after all, the algorithm results obey the normal distribution, but it seems that all blurs have this characteristic), but the fuzzy algorithm has weights Yes, you can start from this angle.

I have never studied computer graphics seriously. . . It's not a good answer, I can only give you a general idea.

I’m still in the learning stage and don’t quite understand it. I hope this article can be helpful to you
