However i read your help in forum, but I couldn't import a mask! in fact I want to make a pic (jpg or tif) as a mask (for example a circle for masking a cylinder) and import it to PIVlab.
How to save and load a mask?
I want to know a complete procedure for above subject.
of course I think that's better to add a circle drawer for making circular masks.
Just found the answer. The .mat file must contain two variables xmask and ymask (saved via MATLAB). Both are cell where a row equals the x or y coordinate of a point and the column the frame (you can just make 1 column and then apply the mask in the GUI for every frame in most cases).
