Function

CuviStatus LUT(const CuviImage& src, const CuviImage& mapping, CuviImage& dst, const CuviStream& stream = CuviStream());

Parameters

Name Type Description src CuviImage& Input Image mapping CuviImage& The look-up table dst CuviImage& Resultant Image stream CuviStream& GPU stream ID for execution

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 );
