Table of Contents
- Given an RGB image, you could get:
- image (png): segmentation, normal images (body + cloth), overlap result (rgb + normal)
- mesh (obj): SMPL-(X) body, reconstructed clothed human
- video (mp4): self-rotated clothed human

ICON's final results |
- If you want to create a realistic and animatable 3D clothed avatar direclty from video / sequential images
- fully-textured with per-vertex color
- can be animated by SMPL pose parameters
- natural pose-dependent clothing deformation

3D Clothed Avatar, created from 400+ images using ICON+SCANimate, animated by AIST++ |
- testing code and pretrained models (*self-implemented version)
- ICON (w/ & w/o global encoder, w/ PyMAF/PARE as HPS)
- PIFu* (RGB image + predicted normal map as input)
- PaMIR* (RGB image + predicted normal map as input, w/ PyMAF/PARE as HPS)
- colab notebook
- training code
- dataset processing pipeline
- Video-to-Avatar module
Please follow the Installation Instruction to setup all the required packages, extra data, and models.
