Weird edge pattern in generated images during training #165

Open manuelmaior29 opened 1 year ago

manuelmaior29 commented 1 year ago

So I am trying to perform a training of the CUT model in order to translate images captured from CARLA Simulator domain to Cityscapes images domain. During training I observed that many of the Fake_B generated images have some weird edges forming at the transition from a ground object to the sky.
Example 1: image

Example 2: image

Some training details:

Is there something related to the training setup that I should consider doing? Should I just wait for more training iterations? Also I noticed that the losses, after the second epoch, started not to really decrease anymore.

Thank you!
