Best way to include size information?

Hi there,

I try to classify black/white images of silhouettes (of animal tracks). Size of the footprints matters a lot, so I want to include this extra information. I have a list with scale factors (which tell me how long one pixel is in reality for each image). I see two options now:

  1. I could make a separate layer for the scale factor data, and then concatenate image and scale factor output (which, I think, is possible using functional API instead of sequential model).

  2. I could program a script that puts black scale bars in a standardised position into every image.

Which of those would be the best approach?

Thanks a lot!
