Adds two images or adds a constant to each pixel of the image.

Function

CuviStatus add(const CuviImage& src1,
               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());


Parameters

Name Type Description
src1 CuviImage& First Input Image
src2 CuviImage& Second Input Image
dst CuviImage& Resultant Image
stream CuviStream& GPU stream ID for execution

Image Type Support

Input 1 Input 2 Output

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);
