Researchers from UCLA and Snap Inc. have developed “Dual-Pivot Tuning,” a personalized image restoration method. This approach uses high-quality images of an individual to enhance restoration, aiming to maintain identity fidelity and natural appearance. It outperforms existing methods, achieving high fidelity and natural quality in restored images. For more information, refer to the researchers’ paper and project.

Personalized Image Restoration with Dual-Pivot Tuning
Image restoration is a complex challenge that aims to create visually appealing and natural images while maintaining the quality of degraded input. Restoring facial images requires a clear understanding of natural images and the individual’s unique features.
Practical Solution: Dual-Pivot Tuning
Dual-Pivot Tuning is a method developed by researchers from the University of California, Los Angeles, and Snap Inc. It customizes image restoration by using a limited set of high-quality images of an individual to enhance the restoration of their degraded images. The primary objectives are to ensure high fidelity to the person’s identity and the degraded input image while maintaining a natural appearance.
The technique involves two steps: text-based fine-tuning to embed identity-specific information within diffusion priors and model-centric pivoting to harmonize the guiding image encoder with the personalized priors. The proposed technique achieves high identity fidelity and natural appearance in restored images, outperforming generic priors regarding general image quality.
Value and Practical Application
The method ensures that the restored images exhibit high fidelity to the person’s identity and the degraded input image while maintaining a natural appearance. It provides consistent restoration while retaining identity and is agnostic to different types of degradation.
