Hi,
In the previous ipp versions I used unique function for 3x3 morphology - ippiDilate3x3_16u_C1IR.
I'm now using ipp18. The new general function - ippiDilateBorder_16u_C1R with 3x3 mask is slower than the old one in about 17%.
Any ideas how to improve performances?
thanks,
Ella

Hi Ella,
could you provide a bit more info: image size, cpu, arch, OS, static/dynamic linking?
the best is the full output from ippGetLibVersion() function.

Hi Igor,
This is the output of ippGetLibVersion() function:
major 2018
minor 0
majorBuild 1
build 56998
targetCpu "core...
Name "ippCore"
Version "2018.0.1 (r56998)"
BuildDate "Oct 10 2017"
I runs the function with 2048x2048 images.
I tested it with different computers, with different CPUs, windows 7 or 10.
Thanks,
Ella

Hi Igor,
Update - we've upgrade the ipp version to the following version:
major 2018
minor 0
majorBuild 4
build 60077
targetCpu core
Name ippCore
Version 2018.0.4 (r60077)
BuildDate Aug 15 2018
This upgrade improved the running time dramatically, and now the dilate function runs faster in my computer (Core(TM) i7-9820HQ). However, in the target computer, the upgrade did not affect the running time, and it still slow.
The target CPU is Xeon E5-6280 b2
Thanks,
Ella

Hi Ella,
could you clarify: do you use DilateBorder as deprecated Dilate algorithm (without operations on border) or with border operations?
In any way thank you for the issue reporting, we will investigate this case.

Hi Pavel,
I send to the function an ROI of the image and use ippBorderInMem.
thanks,
Ella
