[ITK] [ITK-users] Measure execution time of all filters in a mini-pipeline

[Hammond, Emily M]

Hello,

Here is a basic example of how itk::TimeProbesCollectorBase works.

#include "itkTimeProbesCollectorBase.h"

// instantiate a time
itk::TimeProbesCollectorBase timer;

// start timer
timer.Start("NameOfProcess#1");
filterPipeline#1
filter->Update();
timer.Stop("NameOfProcess#1");

timer.Start("NameOfProcess#1");
filterPipeline#2
filter->Update();
timer.Stop("NameOfProcess#2");

// continue until all desired processes are timed

// print out summary report to the terminal
timer.Report( std::cout );

Looks something like this:

          Probe Tag    Starts    Stops             Time (s)
       Complete Code           1            1           80.5431
     Post-processing           1            1           65.6743
  Rigid Registration           1            1           8.35478


Enjoy!

Emily Hammond

Subject: [ITK-users] Measure execution time of all filters in a mini-pipeline

Hi ITK users,

I have large "mini-pipeline" filters (some use 20 or more subfilters,
some of which are minipipelines themselves) and I need to measure how
long each of the subfilters takes to execute.

Is there an easy way I can do that in ITK ?

In an old thread, several solutions were mentioned:
http://www.itk.org/pipermail/insight-developers/2005-December/007447.html
but the thread doesn't say which solution was adopted.

As far as I have understood at the moment, the solution would involve
the use of itk::TimeProbesCollectorBase, but I have found no example of
how to use it. If that is indeed the way to go, can someone direct me to
an example I could start from ?

Best regards,
