Dieses Mal strebe ich eine Geschichte an. Ich wollte es jedoch tun, also habe ich es versucht. Bitte schauen Sie m (_ _) m
Sofort das Ergebnis ,. .. ;. Die Quelle ist übrigens wie folgt. StyleGAN/mayuyu_smile.py / Bitte werfen Sie einen Blick auf den Einfallsreichtum.
** Irgendwie habe ich meinen Mund bewegt! ** ** **
** Ich habe gelacht, aber ich habe ein bisschen Angst (Nein Д`) **
**Jep! Du hast es geschafft! ** ** **
** Das echte Lächeln war noch besser! ** ** **
・ Ich habe versucht, "einen Mann zum Lachen zu bringen" ・ Ich wurde ausgelacht, indem ich die Parameter angepasst habe.
・ Es scheint, dass ein natürliches Lächeln mehr Anpassung und Einfallsreichtum im Video erfordert.
Außerdem füge ich die Quelle von encode_images.py ein, die während des Lernens geändert wurde, um Bilder auszugeben.
