Playing with scaling the bounding box around the face by different x/ y This was not good for characters with distinctive hats or hair or animal ears (such as Holo’s wolf ears). Instead of bothering to tweak it to produce more head-shot-like crops-since if GANs couldn’t master the faces there was no point in making the problem even harder & Similarly, I had left Nagadomi’s face-cropper on the default settings ‘ahoge’ or bunny ears or twin-tails, since those are not faces. The face-cropper centers its crops on the center of a face (like the nose) and, given the original bounding box, will necessarily cut off all the additional details associated with anime heads such as the
Head Crops: Nagadomi’s face-cropper is a face cropper, not a head-cropper or a portrait-cropper. This could be fixed simply by filtering in “safe”-only rather than merely filtering-out “explicit”. Naturally, everyone insisted on joking about TheĮxplicitly- NSFW images make up only ~9% of Danbooru but between the SFW-but-suggestive images and the explicit ones, and Style GAN’s learningĬapabilities, this proved to be enough to make some of the faces quite naughty-looking. Work or to wind up making something like TWDNE, I had not taken theĮffort to crop faces solely from the SFW subset (since no GAN had proven to be good enough to pick up any embarrassing details and I was more concerned withĭanbooru is divided into 3 ratings, “safe”/“questionable”/“explicit”, with “questionable” bordering on softcore. Sexually-Suggestive Faces: because I had not expected Style GAN to The main issues I saw for the faces based on TWDNE feedback were: The Portraits dataset was constructed to train Style GAN anime face models for creating .
