Image acquisition toolbox: Predict how many imgs can be buffered in RAM?

Hello,

I am looking for a way to predict how many frames (approx.) I can capture to the RAM of my computer using the image processing toolbox. I would prefer this over logging to HD.

Is that somehow possible by knowing the size of a frame and knowing the free memory (how...?) Thank you!!

Error event occurred at 14:17:15 for video input object: Mono8-gentl-1.
Unable to allocate memory for an incoming image frame due to insufficient free physical memory.

I am trying to monitor the memory during image acqusition, but there is no logic that I can see.

During capture I am printing this in a loop until the out of memory error occurs:

[bla blubb]=memory;
disp('__')
disp(['mem avail: ' num2str(bla.MemAvailableAllArrays / 1024 /1024/1024)])
disp(['mem matlab: ' num2str(bla.MemUsedMATLAB / 1024 /1024/1024)])
disp(['mem all array: ' num2str(bla.MemAvailableAllArrays / 1024 /1024/1024)])
disp(['mem system avail: ' num2str(blubb.SystemMemory.Available / 1024 /1024/1024)])

The first print out says:

mem avail: 15.4484
mem matlab: 3.986
mem all array: 15.4484
mem system avail: 15.4484

And the last before he error says:

mem avail: 7.8086
mem matlab: 11.6643
mem all array: 7.8086
mem system avail: 7.8086

It doesn't seem that I could use these numbers to predict when the out-of-memory error occurs?

Oh well, maybe this works?

%before the acqusition:
initialAvailableMemory = bla.MemAvailableAllArrays - bla.MemUsedMATLAB
%during acquisition:
remainingMemory = initialAvailableMemory - bla.MemUsedMATLAB
if remainingMemory < X
    stop image acquisition %(but how....)
end
