是否可以从低质量获得高质量视频？

Is possible to get High Quality video from Low Quality ?

推荐答案

请阅读我对该问题的评论。



低质量和高质量视频之间的区别在于细节数量。如果已经消失，则无法恢复它们。

Please, read my comment to the question.

The difference between low and high quality video is the amount of details. You can't restore them if they already gone.

您可以通过插值提高质量。像开源 VLC播放器做。但通常你不能用它赢得很多。



常见的方法是应用一些图像效果，如杰出的CXImage项目。



一切都不太好，所以最好的办法就是变高优质来源视频。 ; - ）

You can improve the quality a bit with interpolation. Like the Open Source VLC Player does. But normally you cant win much with it.

The common way would be to apply some image effects like in the outstanding CXImage project for EVERY frame.

All not very well, so the best way is to get high quality source videos. ;-)

一个明确的否。

没有通用的过程允许将图片或视频的分辨率加倍。

插值只是提高图片大小后平滑度的工具，而且只是概率性的。



顺便说一下，只有on电视剧中，他们在匹配指纹或人脸识别的过程中使用屏幕显示。实际上，屏幕显示正在减慢过程。



我知道只有一个认为接近你想要的东西：

通过拍摄视频序列，您可以通过组合视频中的图片来提高1个移动细节的质量。并且它不起作用，结果没有保险。

A definitive NO.
There is no general purpose process permitting to double the resolution of a picture or a video.
Interpolation is only a tool to improve smoothness after a picture resize, and it is only probabilistic.

By the way, only on TV series, they use screen display in the process of matching finger prints or face recognition. In reality, screen display is slowing the process.

I know only one think that approach what you want:
By taking a video sequence, you can improve the quality of 1 moving detail by combining the picture from the video. And it don't work on anything, and result is not insured.
