From CUVI Wiki

Clamps image pixel values between specified thresholds.


CuviStatus threshold(const CuviImage& src,
                     CuviImage& dst,
                     const CuviScalar& minThresh,
                     const CuviScalar& maxThresh,
                     const CuviStream& stream = CuviStream());


Name Type Description
src const CuviImage& Input Image
dst CuviImage& Destination Image
minThresh const CuviScalar& Minimum value of threshold
maxThresh const CuviScalar& Maximum value of threshold
stream const CuviStream& GPU stream ID for execution

Image Type Support

//Apply threshold on image pixel values
