有算法，而你'绝对不会在Python中找到它们。首先，您可以参考这篇论文：

There are algorithms, and you're definitely not going to find them in Python. To start with, you can take this paper:

Daniel Glasner，Shai Bagon和Michal Irani，单一图像中的超分辨率，在IEEE会议论文集中计算机视觉国际会议，日本京都，2009年。

Daniel Glasner, Shai Bagon, and Michal Irani, "Super-Resolution from a Single Image," in Proceedings of the IEEE International Conference on Computer Vision, Kyoto, Japan, 2009.

这是非常先进的，非常复杂的，并且产生了有希望的结果。如果您将其变为python实现，请将其发布给公众：）

It is very much state of the art, highly sophisticated, and producing promising results. If you ever make it into a python implementation please release it to the public :)
