How to tell if a picture is a Gaussian blur diagram, is there a PHP implementation?

It is not known that the Imagick extension in PHP can be implemented as you say. You refer to the document to see Imagick

This is a bad judgment.

But there is a way of thinking, because the Gaussian blur algorithm generated by the image will have certain characteristics (after all, the results of the algorithm is normal distribution, but it seems that all the ambiguity has this feature), but the fuzzy algorithm is entitled to Heavy, you can start from this point of view.

Computer graphics have not been seriously studied ... Not very good answer, can only give a general idea.

Nanyi-Gaussian fuzzy algorithm

Still in the study phase is not very understand, I hope this article can help you
