How to create the label ground truth when some areas are overlapping?

Hi,

I have 3D images and the coordinates of the labels of objects. I am creating the ground truth volums for each label separately (384x384x160) with roipoly() and drawing the line between points and then maltiplying the label value into each volume. Forexample if I have 4 classes with 1,2,3,4 labels for each object, I have 4 volumes for each, and then add volumes together to get the final ground truth GT=V_obj1+V_obj2+V_obj3+V_obj4 , however, the problem is that some boundary labels are overlapping and a new value is added to the ground truth. I know that I can remove the labels, but this is mixing the value of obj1 and obj2, which have 1 and 2 values and when they add together the overlapping small region gets value=3, with object with value 3.

How can I solve this is there any way to make the things easier and rliable and accurate for creating ground truth?

So you have a single (x,y,z) location that is one label, but is also a different label?

Maybe you should try the Fuzzy Logic Toolbox. I think it has things to handle that kind of situation.
