Function:BlackGammaLUT

Remaps image values according to look up tables but instead of a single table like in LUT, the blackGammaLUT takes separate tables for each channel.

Function

CuviStatus blackGammaLUT(const CuviImage& src, CuviImage& dst, Cuvi16u* redLUT, Cuvi16u* greenLUT, Cuvi16u* blueLUT, const CuviStream& stream = CuviStream());

Parameters

Name Type Description src CuviImage& Input Image dst CuviImage& Resultant Image redLUT Cuvi16u* The look-up table for red channel greenLUT Cuvi16u* The look-up table for green channel blueLUT Cuvi16u* The look-up table for blue channel stream CuviStream& GPU stream ID for execution

Image Type Support

Type 8uC3 16uC3

Example

CuviImage input = cuvi::io::loadImage(path), output; //blackGammaLUT Parameters const int mappingSize = 256; Cuvi16u redLUT[mappingSize], greenLUT[mappingSize], blueLUT[mappingSize]; for (int i = 0; i < mappingSize; i++) { redLUT[i] = 255 - i; greenLUT[i] = i; blueLUT[i] = i; } //blackGammaLUT CuviStatus status = cuvi::colorOperations::blackGammaLUT(input, output, redLUT, greenLUT, blueLUT);
