IP Adapter: Text Compatible Image Prompt Adapter for Text-to-Image Diffusion Models.
The IP-Adapter (Image Prompt Adapter) is designed to enable a pretrained text-to-image diffusion model to generate images with image prompt.
It is a simple yet effective method that can achieve comparable or even better performance than a fully fine-tuned image prompt model.
The key design of IP-Adapter is the decoupled cross-attention mechanism. This mechanism separates the cross-attention layers for text features and image features. The text features are extracted from the text prompt using a pretrained language model, and the image features are extracted from the image prompt using a pretrained image encoder. The two sets of features are then combined using the decoupled cross-attention layers to generate the final image.
(This IP-Adapter with only 22M parameters can achieve comparable or even better performance to a fine-tuned image prompt model. IP-Adapter can be generalized not only to other custom models fine-tuned from the same base model, but also to controllable generation using existing controllable tools. Moreover, the image prompt can also work well with the text prompt to accomplish multimodal image generation.)
IP-Adapter has several advantages over other methods for generating images with image prompt. First, it is lightweight and efficient. It only has 22M parameters, which is much smaller than a fully fine-tuned image prompt model. This makes it faster to train and deploy. Second, it is compatible with other base models, text prompt, and structural controls. This means that it can be used with any pretrained text-to-image diffusion model, and it can be used to generate images with both text prompts and image prompts. Third, it can be used to generate multimodal images. This means that it can be used to generate images that contain both text and images.
IP-Adapter is a promising new method for generating images with image prompt. It is lightweight, efficient, and compatible with other methods. It is a valuable tool for researchers and developers who are working on text-to-image generation.
Here are some additional details about IP-Adapter:
The decoupled cross-attention mechanism is inspired by the Swin Transformer architecture. IP-Adapter is trained using a self-supervised learning objective. IP-Adapter has been evaluated on several benchmark datasets, and it has been shown to outperform other methods.
