3-Create a virtual environment:

virtualenv venv

4-Activate the virtual environment:

source venv/bin/activate

5-Install the project dependencies:

pip install -r requirements.txt

Reshaper

This directory includes scripts to:

Handle the control points on the wavefront.obj meshes to extract body measurements.
Train the Reshaper model to generate 3D avatars from 21 body measurements (adapted from 3D-Human-Body-Shape).
The Avatar class is used in the main file. The Imputer is a method of the Avatar class.

Folder Paths:

Control Points Handling: src/reshaper/cp_handler.py
Reshaper Model Training: src/reshaper/trainer.py
Avatar Class and Imputer: src/reshaper/avatar.py

Extractor

This directory includes the script to build and train an MLP+CNN model to extract body measurements from two (front and side views) full-body images.

Folder Paths:

Model Building and Training: src/extractor/extractor_model_training.py

Input and Output Files

Input files are to be located in data/input_files and consist of:

input_info_extractor.csv
input_front.png
input_side.png
input_data_avatar.csv (generated after the 'extraction' is performed)

Output files are to be stored in data/output_files and may consist of silhouette images extracted and the wavefront.obj file for the avatar.

Data files

To train and use the models, you will need the dataset files for avatars, silhouettes, and body measurements. These files can be downloaded from Zenodo. Make sure to organize the downloaded files following the folder tree presented above.

Generating Avatars from Images

To try the code, navigate to src and run:


python photos2avatar.py
