ProFusion is a new framework for customized text-to-image generation that preserves fine-grained image details without using regularization, as proposed in the paper. ProFusion includes PromptNet, an encoder network, and Fusion Sampling, a method that generates customized images based on a single user-provided image and text requirements. The paper explains how ProFusion works and provides experiments demonstrating its superior performance compared to existing approaches, while still meeting additional user-defined requirements.
