Inter Frame Correspondence Based Feature Propagation

via “inter-frame-correspondence-based-feature-propagation”

Official Pytorch Implementation for "TokenFlow: Consistent Diffusion Features for Consistent Video Editing" presenting "TokenFlow" (ICLR 2024)

Unique: Operates in the diffusion feature space (intermediate UNet activations) rather than pixel space, enabling structure-preserving edits by enforcing consistency at the semantic feature level. Uses inter-frame correspondences computed from the original video to guide feature warping, ensuring edits respect the underlying motion and spatial layout without requiring explicit motion models or video-specific architectures.

vs others: More temporally coherent than frame-independent diffusion editing (which causes flickering) and more efficient than training video-specific diffusion models, achieving consistency by leveraging pre-trained text-to-image models with correspondence-guided feature injection.
