ippiDilateBorder_16u_C1R performance issues

P__Ella — Mon, 18 Mar 2019 14:38:55 GMT

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.

regards, Igor

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
