InstantBooth: Personalized Text-to-Image Generation without Test-Time Finetuning

Recent advances in personalized image generation have enabled pre-trained text-to-image models to learn new concepts from specific image sets. However, these methods often necessitate extensive test-time finetuning for each new concept, leading to inefficiencies in both time and scalability. To address this challenge, we introduce Instant-Booth, an innovative approach leveraging existing text-to-image models for instantaneous text-guided image personalization, eliminating the need for test-time finetuning. This efficiency is achieved through two primary innovations. Firstly, we utilize an image encoder that transforms input images into a global embedding to grasp the general concept. Secondly, we integrate new…
