Logical bitwise AND operation between 2 images or an image and a constant value.

Function

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

CuviStatus AND(const CuviImage& src,
               const Cuvi32s value,
               CuviImage& dst,
               const CuviStream& stream = CuviStream());

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
8uC1 8uC1 8uC1
8uC3 8uC3 8uC3
16uC1 16uC1 16uC1
16uC3 16uC3 16uC3

Sample

Error creating thumbnail: Unable to save thumbnail to destination
First Input Image


Error creating thumbnail: Unable to save thumbnail to destination
Second Input Image


Error creating thumbnail: Unable to save thumbnail to destination
Resultant Image


Example

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

CuviImage gout;

//ANDing
cuvi::arithmeticLogical::AND(gimg1,gimg2,gout);

//The same can be achieved by using logical operators
gout = gimg1 & gimg2;

//Keep only the least 4 bits of the image
gout &= 0x0f;
