Computes absolute difference between pixels of 2 images. Each channel is processed individually.

Function

CuviStatus absDiff(const CuviImage& src1,
                   const CuviImage& src2,
                   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 CuviStream& GPU stream ID for execution

Example

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

//Compute absolute difference
cuvi::arithmeticLogical::absDiff(gimg1,gimg2,gout);
