AN ACCURATE AND AUTOMATIC COLOR CORRECTION METHOD FOR DIGITAL FILMS BASED ON A PHYSICAL MODEL

摘要

A new method for detecting and correcting color-mismatch in digital film is proposed. This method is based on a physical model which accounts for the absorption of light by the different layers of the film. The whole process consists of three sequential stages. Based on the physical model, a robust optical flow method which is invariant to color change is proposed. From the computed flow field, a detection and restoration of distortion regions can be achieved. The obtained results confirm the efficiency of the proposed method.
