pyzbar is just a wrapper around the ZBar library, which does the heavy lifting.
Minimal required resolutions depend on multiple factors, such as the type of barcode you want to decode, the lighting, etc.
You shouldn't need to do any preprocessing, since this is part of ZBar's processing pipeline.
What is the minimum resolution which is required for PyZbar to be able to decode a barcode? Moreover, does it do any contrast maximization inside or it should be done as a pre-processing?
