<br class="">
I am spending quite some time on ObjectByObjectLabelMapFilter, and I don’t really understand conceptually the purpose of the OutputFilter vs the InputFilter. Can you give some explanations, please?<br class="">
<br class="">
Looking at the code, it is bogus if the OutputFilter is different from the InputFilter (in such a case, the pipeline is not fully connected, i.e. the output of the InputFilter is not connected to any internal filter).<br class="">

Thanks,<br class="">
