When (re)extracting faces before training, a resolution can be set.
Does extraction to the exact resolution the model will be using when training, is different than extracting to a higher resolution?
If the model is set to have input resolution 192x192, will I save time (because of skipping the resize step) or enhance quality (because the source image won't be modified from the original, possibly worsening its quality) if I have my dataset also at that resolution?
Or it's the same, anyway, to have my dataset extracted at 256x256 and have my model set as input resolution something like 160x160 or 192x192?
Thanks.
