Add random shear to preprocessing
Julian Moore
I'm not sure that shear corresponds to any effect that might occur naturally - can you clarify why this particular (shear) transform? I might have thought that perspective would be more helpful (see e.g. https://docs.gimp.org/2.4/en/gimp-tools-transform.html).
Could also have barrel/pincushion to reflect common photographic lens issues.
The ability for users to add their image transforms (and/or to a PL library of such) might be interesting...

Julian Moore: while it's questionable that random shear would be naturally occuring in a photo for example, my intention here is that the more possible transforms of
features
(eyes, mouth, nose etcetera) the model gets trained on the better it will be able to generalize those features. Something like that 😅
