Multiplies two images

Function

CuviStatus multiply(const CuviImage& src1,
                    const CuviImage& src2,
                    CuviImage& dst,
                    const CuviStream& stream = CuviImage());

Parameters

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

Image Type Support

Input 1 Input 2 Output
8u 8u 8u
8u 8u 16u
16u 16u 16u
32f 32f 32f

Sample

Error creating thumbnail: Unable to save thumbnail to destination
First Input Image (8-bit)
Error creating thumbnail: Unable to save thumbnail to destination
Second Input Image (8-bit)
Error creating thumbnail: Unable to save thumbnail to destination
Resultant Image (16-bit)

Example

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

CuviImage gout;

//Multiply
cuvi::arithmeticLogical::multiply(gimg1,gimg2,gout);
