Hi, How do I obtain an average ROI from multiple ROIs drawn on different images? Thank you very much for your help.
Images=dir("*ExampleImage.tif");
S_Boundaries=[];
for i=1 :numel(Images)
Image=imread(Images(i).name);
imshow(Image);
p=drawpolygon();
S_boundary{i}=p.Position
S_Boundaries=[S_Boundaries; S_boundary{i}]
end
AverageBoundary = HelpFunction(S_Boundaries)
%HelpFunction would compute an average boundary from multiple boundaries saved as S_Boundaries.

I already did this for someone else. Luckily I saved the code. It's attached.

You can convert your polygons/boundaries into images with the poly2mask() function.
