Image Processing toolbox required...

[Frederic Moisy]

Hi,

Thank you so much William for this great software!

One suggestion: it would be nice to run Pivlab without the image processing toolbox. This would be useful for student projects, since they usually don't have access to this toolbox.

I guess this would mean to re-program the cross-correlation algorithm?

Thanks,

Frederic

Salut Frédéric,

I think the correlation itself is Matlab only, but there are a few other functions that are required to run the GUI.

But are there really many installations without the image processing toolbox? If that is the case, I could try to do a few changes so it can maybe run without this toolbox.

Thank you for your quick answer!

Yes, the Matlab student versions installed in universities (at least in France) have no toolboxes at all. With the increasing popularity of PIV in student projects, having a stand-alone PIVlab would be great.

Best,

Frederic

Ok, then I'll check out how much work this is. I will probably disable some features (e.g. adapthisteq) if no image toolbox is detected.

Sorry to bother, I must say that students could always choose Python :)

More seriously - you could call Python from Matlab and thus keep all the functionality https://blogs.mathworks.com/loren/2020/03/03/matlab-speaks-python/

adapthisteq or CLAHE are all available in scikit-image or OpenCV packages and it's a matter of 2 lines to install and use it.
