EDICT: Exact Diffusion Inversion via Coupled Transformations

2 code implementations CVPR 2023 Bram Wallace, Akash Gokul, Nikhil Naik

EDICT enables mathematically exact inversion of real and model-generated images by maintaining two coupled noise vectors which are used to invert each other in an alternating fashion.
