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
Intermediate Results
ICON's intermediate results
Final ResultsFinal 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
ICON+SCANimate+AIST++
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 Google Colab
  • dataset processing pipeline
  • training and evaluation codes
  • Video-to-Avatar module

Installation

Please follow the Installation Instruction to setup all the required packages, extra data, and models.

Dataset Preprocess

Please follow the Data Preprocess Instruction to generate the train/val/test dataset from raw scans (THuman2.0).

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/hybrik}

# 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/hybrik}
