Who needs ICON?

  • If you want to Train & Evaluate on PIFu / PaMIR / ICON using your own data, please check dataset.md to prepare dataset, training.md for training, and evaluation.md for benchmark evaluation.

  • Given a raw RGB image, you could get:

    • image (png):
      • segmented human RGB
      • normal maps of body and cloth
      • pixel-aligned normal-RGB overlap
    • mesh (obj):
      • SMPL-(X) body from PyMAF, PIXIE, PARE, HybrIK, BEV
      • 3D clothed human reconstruction
      • 3D garments (requires 2D mask)
    • video (mp4):
      • self-rotated clothed human
Intermediate Results
ICON's intermediate results
Iterative Refinement
ICON's SMPL Pose Refinement
Final Results
Image -- overlapped normal prediction -- ICON -- refined ICON
3D Garment
3D Garment extracted from ICON using 2D mask



Installation

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

Dataset

Please follow the Dataset Instruction to generate the train/val/test dataset from THuman2.0

Training

Please follow the Training Instruction to train your own model using THuman2.0

Evaluation

Please follow the Evaluation Instruction to benchmark trained models on THuman2.0

Add-on

  1. Garment Extraction from Fashion Images, supported by ETH Zürich students as 3DV course project.

Demo

cd ICON

# PIFu* (*: re-implementation)
python -m apps.infer -cfg ./configs/pifu.yaml -gpu 0 -in_dir ./examples -out_dir ./results -loop_cloth 100 -export_video

# PaMIR* (*: re-implementation)
python -m apps.infer -cfg ./configs/pamir.yaml -gpu 0 -in_dir ./examples -out_dir ./results -loop_smpl 100 -loop_cloth 200 -export_video

# ICON w/ global filter (better visual details --> lower Normal Error))
python -m apps.infer -cfg ./configs/icon-filter.yaml -gpu 0 -in_dir ./examples -out_dir ./results -hps_type {pymaf/pixie/pare/hybrik/bev} -loop_smpl 100 -loop_cloth 200 -export_video

# ICON w/o global filter (higher evaluation scores --> lower P2S/Chamfer Error))
python -m apps.infer -cfg ./configs/icon-nofilter.yaml -gpu 0 -in_dir ./examples -out_dir ./results -hps_type {pymaf/pixie/pare/hybrik/bev} -loop_smpl 100 -loop_cloth 200 -export_video
