Chapter 24. Using Lookup Tables to Accelerate Color Transformations
Jeremy SelanSony Pictures Imageworks
In feature-film visual-effects production, maintaining interactive feedback of high-quality color operations is extraordinarily beneficial to an artist. On the consumer side, enabling the real-time color correction of video and rendered image streams is becoming an increasingly useful tool to shape media’s thematic “look.” However, directly applying multiple sophisticated color transforms to high-resolution imagery is beyond the real-time capability of modern graphics hardware.
In this chapter, we present an algorithm that leverages three-dimensional lookup tables to enable the real-time color processing of high-resolution imagery. Our approach ...
