               const CuviImage& src2,
               CuviImage& dst,
               const CuviStream& stream = CuviStream());

CuviStatus add(const CuviImage& src,
               const CuviScalar& values,
               CuviImage& dst,
               const CuviStream& stream = CuviStream());

CuviStatus add(const CuviImage& src,
               const Cuvi64f value,
               CuviImage& dst,
               const CuviStream& stream = CuviStream());

Example

CuviImage gimg1 = cuvi::io::loadImage(path);
CuviImage gimg2 = cuvi::io::loadImage(path);
CuviImage gout;

//Add	
cuvi::arithmeticLogical::add(gimg1,gimg2,gout);

//The same can be achieved by using arithmetic operators
gout = gimg1 + gimg2;

//Add a constant value to each pixel of the image
gimg1 += 10;

//Add a different value to each channel
gimg2 += CuviScalar(5,10,3);
