I've been testing the performance of version 7.0 against our current version of IPP, 3.0. While most of the functions we use don't have anynoticeable improvement, some have actually improved. However, theippiFilterMedianappears to take about 25% longer to process the image. I'm surprised by this because ippiFilterMedianCross does not show the same performance hit.
I've tested this with both ippiFilterMedian_8u_C1R andippiFilterMedian_8u_AC4R. Both take about 25% longer to run. Is this expected with the new version or is there something wrong?
IPP 7.0 update 3 has got fix to performance issue of ippiFilterMedian_8u_C1R on Intel 64 platform.
Please refer to bug fix (DPD200203121) list of IPP 7.0 - http://software.intel.com/en-us/articles/intel-ipp-70-library-bug-fixes/
Basic issue could be with unaligned loads from internal buffer (algorithm specific).
Hi Mike Walsh,
I want to make sure that you are linking with right library for particular platform.
Also, Is it possible to share a test case to reproduce this issue, you can use Private option while sending test case.
