SGDM: An Adaptive Style-Guided Diffusion Model for Personalized Text to Image Generation

The existing personalized text-to-image generation models face issues such as repeated training and insufficient generalization capabilities. We present an adaptive Style-Guided Diffusion Model (SGDM). When provided with a set of stylistically consistent images and prompts as inputs, SGDM can generate images that align with the prompts while maintaining style consistency with the input images. SGDM first extracts features from the input style image and then combines style features from different depths. Last, style features are injected into the noise generation process of the original Stable Diffusion (SD) model by the style-guided module we propose. This strategy fully leverages the generative and generalization capabilities of the pre-trained text-to-image model to ensure the accuracy of the generated image's content. We present a dataset construction method suitable for style personalized generation tasks of this kind, enabling the trained model to generate stylized images adaptively instead of re-training for each style. We also present an evaluation metric, StySim, to measure the style similarity between two images, and this metric shows that the style personalization capability of SGDM is the best. And metrics such as FID, KID, and CLIPSIM indicate that SGDM maintains good performance in text-to-image generation.
