Fast 3D LUT on CUDA
3D LUT Transform is massively used for color grading and gamut mapping applications. To solve the task of 3D LUT grading, we have developed fast kernels that run on existing CUDA hardware from NVIDIA. We have implemented various formats for 3D LUTs and achieved very high performance for color grading.
3D LUT Transform Features
Hardware and software
Performance for 2.5D and 3D LUT Transforms on CUDA
Test images: 16-bit RGB, 2432×1366 (2.5K) and 4032×2192 (4K), fast trilinear interpolation
We have designed that software as a part of our CUDA image & video processing SDK. Now our customers have opportunity to use fast 3D LUT transforms on CUDA in their realtime color grading applications with user-defined 3D LUTs.
