There is a function nppiLUT_16u_C1R for 16 bit image. 16 bit image has 65536 brightness levels. But the function supports 1024 levels maximum, according to nvidia documentation(https://docs.nvidia.com/cuda/npp/group__image__color___l_u_t.html). I guess there is some sort of tricky method to by pass such limitation. But I did not manage to find any example of implementation of the function. Could you please help me?
