ECON is designed for "Human digitization from a color image", which combines the best properties of implicit and explicit representations, to infer high-fidelity 3D clothed humans from in-the-wild images, even with loose clothing or in challenging poses. ECON also supports multi-person reconstruction and SMPL-X based animation.

d-BiNI jointly optimizes front-back 2.5D surfaces such that: (1) high-frequency surface details agree with normal maps, (2) low-frequency surface variations, including discontinuities, align with SMPL-X surfaces, and (3) front-back 2.5D surface silhouettes are coherent with each other.

# For single-person image-based reconstruction (w/ l visualization steps, 1.8min)
python -m apps.infer -cfg ./configs/econ.yaml -in_dir ./examples -out_dir ./results
# For multi-person image-based reconstruction (see config/econ.yaml)
python -m apps.infer -cfg ./configs/econ.yaml -in_dir ./examples -out_dir ./results -multi
# To generate the demo video of reconstruction results
python -m apps.multi_render -n <file_name>

Animation with SMPL-X sequences (ECON + HybrIK-X)
# 1. Use HybrIK-X to estimate SMPL-X pose sequences from input video
# 2. Rig ECON's reconstruction mesh, to be compatible with SMPL-X's parametrization.
# 3. Animate with SMPL-X pose sequences obtained from HybrIK-X, getting <file_name>_motion.npz
# 4. Render the frames with Blender (rgb-partial texture, normal-normal colors), and combine them to get final video
python -m apps.avatarizer -n <file_name>
python -m apps.animation -n <file_name> -m <motion_name>

}We also provide a UI for testing our method that is built with gradio. This demo also supports pose&prompt guided human image generation! Running the following command in a terminal will launch the demo:
git checkout main
python app.pyThis demo is also hosted on HuggingFace Space
Please firstly follow the TEXTure's installation to setup the env of TEXTure.
# generate required UV atlas
python -m apps.avatarizer -n <file_name> -uv
# generate new texture using TEXTure
git clone https://github.com/YuliangXiu/TEXTure
cd TEXTure
ln -s ../ECON/results/econ/cache
python -m scripts.run_texture --config_path=configs/text_guided/avatar.yamlThen check ./experiments/<file_name>/mesh for the results.
