DiffMorpher: Unleashing the Capability of Diffusion Models for Image Morphing

no code implementations12 Dec 2023 Kaiwen Zhang, Yifan Zhou, Xudong Xu, Xingang Pan, Bo Dai

Our key idea is to capture the semantics of the two images by fitting two LoRAs to them respectively, and interpolate between both the LoRA parameters and the latent noises to ensure a smooth semantic transition, where correspondence automatically emerges without the need for annotation.
