I know that my question or request may be odd. My friend's car stolen and he is using it for his living :(. Fortunately we got a video from a cam that showing the crime and the thieves, the video shows another car used by the thieves, some of them ride my friend's car and others ride another red car, however, the video resolution is very low and I cannot even got the red car license number. Can any one here who know how to fine tune photos and video resolution help me. I am very sorry for my question and sending my apology to the admin(s) I knew that forum is not used for such question(s) but indeed I need help

What I have tried:

I just used movie maker to extract a photo for the red car. I tried many online image tuner and the result was not as expected

推荐答案

尽管你在电视和电影中看到的东西 - 尤其是NCIS和CSI - 你无法增强低分辨率视频以获得高分辨率视频和读取号牌 Tha t需要发明不存在的信息：每平方英寸（例如）10 x 10像素的低分辨率图像包含100条信息，每条信息都是描述该像素的单个RGB或HLS值，而不是其他。要将其转换为100 x 100的高分辨率图像，您必须将原始图像中一个像素的值复制到新图像中的100个像素（即10 x 10平方），并且不会添加任何图像信息 - 当然不是任何你可以改进生产警察会接受的红色车牌号的东西，因为你必须使用太多，太多的猜测，并且可能得到你想要的任何数字！



这就是为什么在现实世界中安全摄像机坏人的镜头一般都很差，如果他们是男性或女性你只能真正做出来 - 增强低分辨率图像来制作尖锐的高分辨率不起作用，因为信息没有压缩到低分辨率图像，它只是不存在。

Despite what you see on the TV and in movies - especially NCIS and CSI - you cannot "enhance" low resolution video to get high resolution video and "read a number plate". That requires inventing information that doesn't exist: a low resolution image that has (say) 10 x 10 pixels per square inch contains 100 pieces of information, each of which is a single RGB or HLS value which describes that pixel, and no other. To convert this to a high resolution image that has 100 x 100 you would have to copy the value of one pixel in the original to 100 pixels in the "new" image (i.e. a 10 x 10 square) and that doesn't add any information - certainly not anything you could "refine" to produce anything that the police would accept as "the red car number plate" because you would have to use far, far too many guesses and could probably get any number you wanted!

That's why in the real world security camera footage of the bad guys is generally so poor that you can only really make out if they are male or female - enhancing low res images to produce sharp high res ones doesn't work as information isn't "compressed" into the low res image, it just doesn't exist.
