PurifyGen: A Novel Approach for Safe Text-to-Image Generation
Analysis
This paper introduces PurifyGen, a training-free method to improve the safety of text-to-image (T2I) generation. It addresses the limitations of existing safety measures by using a dual-stage prompt purification strategy. The approach is novel because it doesn't require retraining the model and aims to remove unsafe content while preserving the original intent of the prompt. The paper's significance lies in its potential to make T2I generation safer and more reliable, especially given the increasing use of diffusion models.
