CVPR 2022
News 🚩
- [2022/03/05] PIXIE (SMPL-X), PARE (SMPL), PyMAF (SMPL) are all supported as optional HPS.
- [2022/02/07]
is ready to use.
Table of Contents
Who needs ICON?
- 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 intermediate results |
  |
| ICON's normal prediction + reconstructed mesh (w/o & w/ smooth) |
- 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++ |
TODO
- testing code and pretrained models (*self-implemented version)
- ICON (w/ & w/o global encoder, w/ PyMAF/PIXIE/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
Installation
Please follow the Installation Instruction to setup all the required packages, extra data, and models.
Demo
cd ICON/apps
# PIFu* (*: re-implementation)
python infer.py -cfg ../configs/pifu.yaml -gpu 0 -in_dir ../examples -out_dir ../results
# PaMIR* (*: re-implementation)
python infer.py -cfg ../configs/pamir.yaml -gpu 0 -in_dir ../examples -out_dir ../results
# ICON w/ global filter (better visual details --> lower Normal Error))
python infer.py -cfg ../configs/icon-filter.yaml -gpu 0 -in_dir ../examples -out_dir ../results -hps_type {pixie/pymaf/pare}
# ICON w/o global filter (higher evaluation scores --> lower P2S/Chamfer Error))
python infer.py -cfg ../configs/icon-nofilter.yaml -gpu 0 -in_dir ../examples -out_dir ../results -hps_type {pixie/pymaf/pare}More Qualitative Results
