Color Correction Acceleration Using a Color Cube and OpenCL

Abstract

The article deals with the problem of real time color correction on modern but not dedicated video hardware, suggesting a new implementation of fast algorithm for color transformation utilizing 3D look-up tables. We focus on highly parallel nature of the proposed method and employ the GPU to perform the color calculations side-by-side. The paper is comparing the performance of the implementation of the algorithm on the CPU and on the GPU.
