Error -213 While Calling ippiFilterBorderInit_64f

[amini__roham]

Greetings,

this is my first post in this forum so please bear with me. While exploring the FilterBorder family of functions, I used ippRndFinancial round mode with ippiFilterBorderInit_64f. However it returned error -213. My question is can ippRndFinancial be used with ippiFilterBorderInit_64f (the documentation did not mention anything regarding this)? Attached is my Test.cpp file.

Thanks

thanks for the issue, we will check. Did you check if you see the same issue with ippRndZero or other modes?

Dear Gennady,

Yes i tried all rounding modes. Same error with ippRndZero.  However,the function executed successfully with ippRndNear.

Thanks

thanks, we will investigate the cause of the issue and keep you informed with the status.

ipptypes.h defines status of this operations: ippStsRoundModeNotSupportedErr    -213 /* Rounding mode is not supported. */

What kind of rounding mode do you need for supporting this function?

Hello,

thanks for reporting, yes, it is the problem in the IPP documentation and in the ippi.h header file. Actually this function supports only the ippRndNear mode. We will correct documentation. If you need supporting other round modes please submit an official request through https://supporttickets.intel.com/

Dear Pavel and Gennady,

thanks for your replies. I decided to use ippRndNear rounding mode. While exploring the FilterBorder family of functions, I also observed that each kernel data type only supports certain image data types as shown below.

kernel data type    supported image data types

    ipp16s                   ipp8u, ipp16u, ipp16s

    ipp32f               ipp8u, ipp16u, ipp16s, ipp32f

    ipp64f                              ipp64f

Wrong combination of kernel data type and image data type results in error -59 (ippStsDataTypeErr). If this is indeed the correct behavior for this family of functions, I was unable to find any documentation about it as well. (as a suggestion, this information could be added to the documentation for the sake of completeness.)

thanks
