Example

CuviImage* gimg = new CuviImage(size,img->depth,img->nChannels); CuviImage* gout = new CuviImage(size,img->depth,1); gimg->upload(img->imageData,img->widthStep); //Transform coefficients float* coff = new float[3]; coff[0]= 0.3f; coff[1]= 0.59f; coff[2]= 0.11f; //function call cuvi::colorOperations::color2Gray(gimg,gout,coff);
