InteractDiffusion: Interaction Control in Text-to-Image Diffusion Models
CoRR(2023)
摘要
Large-scale text-to-image (T2I) diffusion models have showcased incredible
capabilities in generating coherent images based on textual descriptions,
enabling vast applications in content generation. While recent advancements
have introduced control over factors such as object localization, posture, and
image contours, a crucial gap remains in our ability to control the
interactions between objects in the generated content. Well-controlling
interactions in generated images could yield meaningful applications, such as
creating realistic scenes with interacting characters. In this work, we study
the problems of conditioning T2I diffusion models with Human-Object Interaction
(HOI) information, consisting of a triplet label (person, action, object) and
corresponding bounding boxes. We propose a pluggable interaction control model,
called InteractDiffusion that extends existing pre-trained T2I diffusion models
to enable them being better conditioned on interactions. Specifically, we
tokenize the HOI information and learn their relationships via interaction
embeddings. A conditioning self-attention layer is trained to map HOI tokens to
visual tokens, thereby conditioning the visual tokens better in existing T2I
diffusion models. Our model attains the ability to control the interaction and
location on existing T2I diffusion models, which outperforms existing baselines
by a large margin in HOI detection score, as well as fidelity in FID and KID.
