How to convert night image to day image? I have set of night images which I will be using for self driving. But I want to convert those images into day images. I have developed algorithm based on day image but it is not good for night images , so I want to convert night images to day images then feed into the network. As far as I have explored image colourization techniques of grey scale image ( converting night image to black and white and then coloring it) ànd night to day style transfer using GANs. Is it possible to achieve the goal with the above two mentioned techniques or you can also suggest any other way.

One problem with this is that dark images simply contain less information. Anyone with a background in photography will tell you it’s easier to decrease exposure on a bright image than increase exposure on a dark one (you can’t create what’s not there but you can throw away information you have). If you want all images on the same playing field, perhaps do the reverse. Or, try to extract only edges or high contrast regions from all images. Or, model them differently.
