need clarification on the pre-processing rules in open division 

Hi WG,
The pre-processing rules in open division is kind of ambiguous. 
I'd like to know if the resized image size in included in pre-processing? So that can it be changed in open division? For example in visual wake words, the input image is resized to 96x96, can we change to 128x128 or 48x48 in open division?
