ippiThreshold_Val_8u_C1IR

[fzhe]

Hi, there,

When I ran the following code,

////////////////////////////////////////
Ipp8u img1[2][2]={0,1,2,3};
IppiSize sz1={2,2};

int stride = 2;
IppStatus s1 = ippiThreshold_Val_8u_C1IR(&(img1[0][0]),stride,sz1,0, 1, ippCmpGreaterEq);//ippCmpEq);
///////////////////////////////////////////////
the return status (s1) is "ippStsNotSupportedModeErr" instead of ippStsNoErr.

Please advice on what is wrong with the code.

Thanks.

Fan,

if you'll look at description of this function in ippi manual you'll find that:

ippCmpOp

The operation to use for comparing pixel values and the threshold. Comparison for either less than or greater than can be used.

Yes. I did try equal and greater than. Both of them produced that error status.

Really? I recommend you to submit issue report to Intel Premier Support

Please specify what version of IPP do you use and what platform, processor and OS.

Tech support duplicated the problem and escalated it already. Since you gave me better answers than I got from tech-support, I want to try the forum too.

Thanks anyway.

Thanks you, we will check if it is wrong documentation issue or it is bug in function's implementation.
