Nerfies: Deformable Neural Radiance Fields

What is Nerfies: Deformable Neural Radiance Fields ?

Nerfies: Deformable Neural Radiance Fields is a machine learning model designed to create 3D avatars from casual video inputs. It utilizes advanced neural rendering techniques to generate photorealistic 3D portraits by analyzing movement and appearance in video data. This technology extends traditional neural radiance fields (NeRF) by incorporating deformable components, allowing it to better capture non-rigid deformations like facial expressions and body movements. The result is a highly detailed and dynamic 3D representation of a person.

Features

• Photorealistic 3D Avatars: Generates high-quality 3D models that closely resemble the input subject.
• Dynamic Deformation Handling: Captures subtle movements and expressions in videos for realistic animations.
• Casual Video Input: Works with unstructured video clips, making it accessible for everyday use.
• User-Friendly Interface: Designed for ease of use, even for users without extensive technical expertise.
• Customizable Output: Allows adjustments to lighting, pose, and other parameters for tailored results.

How to use Nerfies: Deformable Neural Radiance Fields ?

1. Capture or Upload Video: Record or upload a short video clip of the subject from multiple angles.
2. Process with Nerfies: Input the video into the Nerfies tool for analysis and 3D modeling.
3. Generate 3D Avatar: The model processes the video data and creates a deformable neural radiance field.
4. Refine and Export: Adjust settings if needed and export the 3D avatar for use in various applications.
