I have tried to find a C source code example using NPP nppiLUT_Cubic_8u_C4IR method that uses a 3D LUT to modify an image. I have found zero examples after hours many,many hours of searching. So my question is does anyone actually use these functions? Are there any usage examples available? I don’t really want to use OpenGL as I would like to have our whole project use the NPP library and Cuda.
Thanks in advance.
