This is a demo for **ReVersion: Diffusion-Based Relation Inversion from Images**
[[Paper](https://arxiv.org/abs/2303.13495)] | [[Project Page](https://ziqihuangg.github.io/projects/reversion.html)] | [[GitHub Code](https://github.com/ziqihuangg/ReVersion)] | [[Video](https://www.youtube.com/watch?v=pkal3yjyyKQ)]
It is recommended to upgrade to GPU in Settings after duplicating this space to use it. <a href="https://huggingface.co/spaces/Ziqi/ReVersion?duplicate=true"><img src="https://bit.ly/3gLdBN6" alt="Duplicate Space"></a>

ReVersion

DETAILDESCRIPTION='''
We propose a new task, **Relation Inversion**: Given a few exemplar images, where a relation co-exists in every image, we aim to find a relation prompt **\<R>** to capture this interaction, and apply the relation to new entities to synthesize new scenes.
Here we give several pre-trained relation prompts for you to play with. You can choose a set of exemplar images from the examples, and use **\<R>** in your prompt for relation-specific text-to-image generation.

"T4 small" is sufficient to run this demo.
