Product Information
Key Features of Key-Locked Rank One Editing for Text-to-Image Personalization - NVIDIA Research
Perfusion enables more animate results, with better prompt-matching and less susceptibility to background traits from the original image. It also allows for efficient control of the visual-textual alignment at inference time.
Key-Locking Mechanism
A mechanism that 'locks' new concepts' cross-attention Keys to their superordinate category, allowing for more visual variability and accurately portraying the nuances of an object or activity.
Gated Rank-1 Approach
An approach that controls the influence of a learned concept during inference time and combines multiple concepts.
Efficient Control of Visual-Textual Alignment
Perfusion allows for efficient control of the visual-textual alignment at inference time, enabling users to balance visual-fidelity and textual-alignment with a single trained model.
One-Shot Personalization
Perfusion can generate images with both high visual-fidelity and textual-alignment when training with a single image.
Zero-Shot Transfer to Fine-Tuned Models
A Perfusion concept trained using a vanilla diffusion-model can generalize to fine-tuned variants.
