               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,

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);
