Bitwise XOR operation of an image with another image or a constant value.

Function

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

CuviStatus XOR(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

First Input Image
Second Input Image
Resultant Image


Example

CuviImage input1 = cuvi::io::loadImage(path);
CuviImage input2 = cuvi::io::loadImage(path);
CuviImage output;

//XOR Operation
cuvi::arithmeticLogical::XOR(input1,input2,output);

//The same can be achieved by using XOR operator
output = input1 ^ input2;

//Inverting last 4 bits of each pixel of the image
output ^= 0x0f;
