Key Idea

The core concept of IC-LoRA is to concatenate both condition and target images into a single composite image while using Natural Language to define the task. This approach enables seamless adaptation to a wide range of applications.

Features

• Task-Agnostic Framework: IC-LoRA serves as a general framework, but it requires task-specific fine-tuning for diverse applications.
• Customizable Image-Set Generation: You can fine-tune text-to-image models to generate image sets with customizable intrinsic relationships.
• Condition on Image-Set: You can also condition the generation of a set of images on another set of images, enabling a wide range of controllable generation applications.

For more detailed information and examples, please read our Paper or visit our Project Page.

Getting Started

You can directly use the open-source AI-Toolkit to train IC-LoRA models. We have provided sample training data with a configuration file in this repo:

• Configuration File: config/movie-shots.yml (place it in the config/ directory of AI-Toolkit)
• Sample Training Data: data/movie-shots.zip (extract it to data/movie-shots of AI-Toolkit)

After installing the necessary dependencies and setting up AI-Toolkit, you can start training by running:

python run.py config/movie-shots.yml

The training runs on a single GPU with at least 24GB of memory (adjust the resolution parameter in config/movie-shots.yml for different GPU memory limits). The training should complete in a few hours.

Prompt for Multi-Scene Image Captioning

As a reference, we provide an example prompt used to generate captions for multi-scene images:

Create a short description of this three-scene image featuring movie shots, beginning with the prefix [MOVIE-SHOTS] for the entire caption, followed by an overall summary of the image. Each scene detail should flow within the same sentence, with specific markers [SCENE-1], [SCENE-2], [SCENE-3], indicating the start of each scene’s description. Name the role(s) with random name(s) if necessary, and wrap the name(s) with "<" and ">". Ensure the entire description is cohesive, flows as one sentence, and remains within 512 words.

MODEL ZOO
