ippiCrossCorrNormGetBufferSize parameters

b_k_ — Fri, 22 Apr 2022 06:17:10 GMT

Hello!

I have a question about ippiCrossCorrNormGetBufferSize .

The documentation for the function shows it takes 4 parameters:

IppStatus ippiCrossCorrNormGetBufferSize (IppiSize srcRoiSize, IppiSize tplRoiSize, IppEnum algType, int* pBufferSize);

However, in the example forCrossCorrNorm the GetBufferSize function is called with 5 parameters.

The extra parameter is ipp32f:

status = ippiCrossCorrNormGetBufferSize(srcRoiSize, tplRoiSize, ipp32f, funCfg, &bufSize);

The example does not compile. The error is:

ippiCrossCorrNormGetBufferSize': function does not take 5 arguments

We are using Ipp 8.1 but the documentation is the same for the latest relaeas.

The code works well for ipp8u images without the ipp32f parameter.

I guess it is important to communicate the pixel/element size to the GetBufferSize function.

How should it be done?

Hi,

Thanks a lot for reaching us. You are right, the extra parameter (ipp32f) should be moved in the sample code. We will update the sample code in documentation.

Have a nice day!

Thank you for the reply.

So if I understand correctly the call to ippiCrossCorrNormGetBufferSize should be

status = ippiCrossCorrNormGetBufferSize(srcRoiSize, tplRoiSize, funCfg, &bufSize);

regardless of the data type of source and tmplate images?

Yes, the API calculates buffer size depends on srcRoiSize and tplRoiSize.

Have a good day!
