Example
CuviImage input = cuvi::io::loadImage(path), output;
//Create LUT on host
const int mappingSize = 256;
unsigned char mappingValues[mappingSize];
//Initialize LUT with values which invert the image values
for(int i=0; i<mappingSize; i++)
mappingValues[i] = 255 - i;
//Create and upload LUT matrix on device
CuviImage mapping(mappingSize,1, CUVI_8UC1);
mapping.upload(mappingValues, sizeof(mappingValues));
cuvi::colorOperations::LUT( input, mapping, output );
