A while back I analyzed 35000 images in PIVlab on my pc. It took 2 days, but worked just fine (my system has 8GB ram). This week I'm trying to analyze 12000 images, however, Matlab runs out of memory after just 200 images. I can't figure out why this happens. Does anyone have a clue?
I applied a mask and a region of interest, just like my previous analysis.
Hm, I don't really have an idea... Are you using much smaller interrogation areas or much larger images than before? I never ran out of memory yet (I was analyzing many sets of 10.000 image pairs each), and I was always using the command line version.
I tried your option regarding the command line version. I analyzed a data set of 15000 images without any problem (memory usage around 800mb).
Today I started a new analyses, concerning 35000 images. However, after only 300 images Matlab consumes 3000mb ram. The only difference with the prior analysis is the slidely larger ROI, however, the mask covers a larger area of the image. I'm surprised!
that is really strange... I am just running an analysis with 720 images (I don't have more available right now...), and the memory usage is around 450 MB all the time, without any trend...
I don't have any idea how to help here however... :-(
