Why am i getting this errors below? What does it mean?

Attempted to access bbox(3); index out of bounds because numel(bbox)=0.

Error in InitShape (line 18) a = 0.80*bbox(3)/(max(rshape(1:n))-min(rshape(1:n)));

Error in Demo (line 37) test_init_shape = InitShape(bbox,refShape);

Because you don't have anything in the array bbox as the error message says.

Now WHY that might be so is indeterminate since you showed no context. One presumes maybe a file input operation may have failed to return any data and your script/function didn't check for such a failure at the time...but it could be any of a number of other reasons.

The crystal ball is murky, sorry...

I think it is because i don't have the min and max size of the object i want to detect but i don't know how. Can you help me with that?

Not without anything more to look at, no...

The error means that bbox is empty. That is why you cannot acces bbox(3).
