how to replace zero values in an image with another arbitrary value

[Kadir_Kirtac]

Hello, I want to replace zero values in a 32f image with another floating point value. I tried to combineippiCompareC with ippiThreshold function but couldn't succeed. Is there any simple solution for this purpose?

Hi Kadir,

Could you clarify theexact problem when combine the ippiCompareC and ippiThreshold.

It was expected the functions like ippiThreshold_Val can set the pixel which meet some condition ( value=0.0f)to other floating point value.

IppStatus ippiThreshold_Val_(const Ipp* pSrc, int srcStep,
Ipp* pDst, int dstStep, IppiSize roiSize, Ipp threshold,
Ipp value, IppCmpOp ippCmpOp);

but could bebecause that zero values in floating point value is hard to defined?

Regards,
YingH.

Sorry I have completely missed outippiThreshold_Val. I was just trying to use Threshold_LTVal, Threshold_GTValetc..

That will exactly solve the problem.

Best regards.
