Mismatch between legacy90ippiFilterColumn_32f_C1R(ipp legacy) and ippiFilterColumn_32_C1R(ipp7.0)

Hi,

I was using ippiFilterColumn_32_C1R earlier now currently upgrading with ipp2017. I have replaced ippiFilterColumn_32_C1R with legacy90ippiFilterColumn_32_C1R API's and result is not matching, while ippiFilterRow_32_C1R is working fine.

 

I have attached sample images, kernel value and output results.

  • Kernels -> gauss.txt & dgauss.txt
  • Sample images -> lighthouse.tif & houses.tif
  • output images 
    • with gauss.txt kernel -> light_gauss_legacy.tif(from ipp legacy) & light_gauss_old.tif(from old ipp7.0)
    • with dgauss.txt kernel -> houses_dgauss_legacy.tif(from ipp legacy) & houses_dgauss_old.tif(from old ipp7.0)

 

Please provide me some workaround to fix this issue and what is the reason for mismatch.

 

Regards
Ubhay
