Function:Multiply

Multiplies image with another image or constant value(s).

Function

CuviStatus multiply(const CuviImage& src1, const CuviImage& src2, CuviImage& dst, const CuviStream& stream = CuviStream()); CuviStatus multiply(const CuviImage& src, const CuviScalar& values, CuviImage& dst, const CuviStream& stream = CuviStream()); CuviStatus multiply(const CuviImage& src, const Cuvi64f value, CuviImage& dst, const CuviStream& stream = CuviStream());

Parameters

Example

CuviImage gimg1 = cuvi::io::loadImage(path); CuviImage gimg2 = cuvi::io::loadImage(path); CuviImage gout; //Multiply cuvi::arithmeticLogical::multiply(gimg1,gimg2,gout); //Multiply with a constant value gout *= 4; //Multiply each channel with a different value gout *= CuviScalar(3,5,6);
