OpenCL
Usage
output = intlut_ATI(input, lookupTable);
Class Support
ushort is supported for input, output and lookupTable.
Algorithm
Since the algorithm of intlut is to use input pixel values as indices to a lookup table to generate output pixels,
data fetching is the major performance bottleneck. Our implementation focus on full utilization of ATI device
memory bandwidth by fetching vector data types.
