Idea2Img: Automating Image Design and Generation with Self-Refinement

Introducing Idea2Img: A Multimodal Framework for Image Design and Generation

The goal of image design and generation is to create an image based on an idea provided by the user. This can include reference images or specific instructions for the design’s intended application. Currently, humans rely on text-to-image (T2I) models to generate images based on detailed descriptions. However, researchers are now exploring the possibility of training systems to have the same self-refinement ability as humans, using large multimodal models (LMMs).

Self-refinement is a natural tendency for humans when facing unknown or difficult tasks. It allows us to continually improve our methods. This concept has been successfully applied to natural language processing tasks, such as acronym generation and text-based environment exploration, using large language model (LLM) agent systems.

However, challenges arise when dealing with multimodal content that combines images and text. To address these challenges, the researchers at Microsoft Azure focused on image design and generation as a way to study the capabilities of iterative self-refinement. They developed Idea2Img, a multimodal framework that allows for the automatic development and design of images.

Idea2Img combines the power of an LMM called GPT-4V(vision) with a T2I model. GPT-4V generates text prompts based on the user’s input and previous feedback. It then selects the most promising draft image from a set of options and provides feedback on how to improve the prompts for better image generation. This iterative self-refinement process is facilitated by Idea2Img’s built-in memory module, which keeps track of exploration history.

The advantage of Idea2Img over traditional T2I models is its ability to accept design directions instead of detailed descriptions, accommodate multimodal input, and produce images with higher semantic and visual quality. The team conducted user preference studies using Idea2Img and various T2I models, and found significant improvements in user preference scores, indicating the effectiveness of Idea2Img.

In conclusion, Idea2Img is a powerful tool for image design and creation. It utilizes the capabilities of LMMs and T2I models to offer a more efficient and user-friendly approach. With its self-refinement ability and improved features, Idea2Img stands out as an invaluable resource for users in need of automated image generation.
