推荐答案

我认为不可能，对不起。 Jpeg是一种有损压缩格式，这意味着无论何时压缩图像，原始图像中的某些信息都会丢失。您无法从文件中恢复原始质量。

必须有一些算法可以对平滑度，亮度，对比度等起作用，并且可能会产生更好的质量感;但这并不能保证，相同的算法可能会导致一个图像的结果可接受，而另一个图像则不可接受。

I don't think it is possible,, sorry. Jpeg is a lossy compression format, it means that whenever an image is compressed, some informations in the original image are lost. You cannot recover the 'original' quality from the file.
There must be some algorithms that can act on smoothness, brightness, contrast, etc., and may result in a better sensation of quality; but that is not guaranteed, and the same algorithm could lead to an acceptable result for one image, and a non-acceptable for another one.
