Recently, Meta officially launched an open-source AI virtual try-on framework named Leffa. This framework aims to enhance the user dressing experience by generating new images, allowing users to switch between different clothing and poses based on a reference image. Compared to previous methods, Leffa excels in detail retention and reducing image distortion. The launch of Leffa brings new possibilities for online shopping and virtual try-ons. Users only need to upload a reference image, and the system can generate an entirely new outfit effect based on that image.
