The short answer to your question is that the GUI doesn't have a way to enable parallel at the moment. The long answer is that we're currently experimenting with several ways to decompose the DIC problem to make the best use of parallel processing. At a minimum, we'd like to make better use of GPUs and threading, but we haven't settled on a particular algorithm to do so. Once the dust settles on how we will make use of parallel processing it will likely happen seamlessly for the GUI.
Thank you for your reply. And I have another question which is how to calibrate the image, i.e. tell the software the scale of the image (pixel: actual length). Because I would like to get the results related to the actual displacement or strain.
If you are doing 2d correlation, you can calibrate the analysis using calibration images and the calibration tool in the GUI. If you check the box that says "calibrate results" you will see a button for "perform cal". For this you will need several images of a calibration pattern with one image of the calibration pattern in the plane of the sample you are analyzing (this is the pose estimation frame). Once the cal is complete if you accept the cal results the results from your DIC measurements will now be in terms of physical units.
Hello, any update on this? I am running DICe for 200-300 images with size of 6000x4000. Without GPU parallelization, it took 2+ hours. I need to do a total of 12 analysis, which would make 24 hours of computing time. Also the latest pre-release does not have many ROI options in it.
Hi,
Thanks for your software and contribution. I am using the GUI of DICe to process an image sequence. And I did not see the option of parallel processing in GUI. So how to toggle on the multi-processing function using GUI?
Regards.
