I'm using 144x144 now, but i was wondering if i should cut out the mouth and chin region, so it would not be affected so much with facial hair growth. Right my trained dataset is out of date the moment someone shaves of their beard. It's to user intrusive (and useless for any kind of monitoring to train every time this changes.
Also - would it be a good idea to segment out the face from the background on a training image? This way clothes would not be trained, and only the face.
