The task of color grading (or color correction) for film and video is significant and complex, involving aesthetic and technical decisions that require a trained operator and a good deal of time. ...
In order to determine whether deep neural networks are capable of learning this complex aesthetic task, we compare two network frameworks-a classification network, and a conditional generative adversarial ...
Even more critically, the expertise involved in performing the task of color grading is beyond the knowledge, budget, or time of most amateur filmmakers, YouTube producers, home video makers, and so on ...
