Sample
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); |
