What is UniPortrait
UniPortrait is an AI image personalized editing tool launched by Alibaba. It can convert photos into anime style and supports multi-person group photos and face-swapping technology. Through advanced "ID embedding" and "ID routing" technologies, UniPortrait can accurately identify and modify each person's facial features even in multi-person group photos, avoiding confusion. UniPortrait can not only change the photo style, but also adjust features such as a person's age and expression, providing diversified image customization services.
