Producing DPG from a new diagram

Hi,

I would like to generate diagram parsing graph (DPG) from pathway diagrams that I extracted from biomedical literature. Can I use this implementation to do that?

I checked the original paper, but could not reproduce the preprocessing steps such as finding blobs and arrows or potential relations (i.e. section 7.1 and 7.2 ) for DSDP-Net.

Best Regards,
Satoshi
