How to Run

• Download and prepare SMPL model and TailorNet data from dataset repository.
• Set DATA_DIR and SMPL paths in global_var.py file accordingly.
• Download trained model weights in a directory and set its path to MODEL_WEIGHTS_PATH variable in global_var.py.
  • old-t-shirt_female_weights (4.1 GB)
  • t-shirt_male_weights (2.0 GB)
  • t-shirt_female_weights (2.0 GB)
  • shirt_female_weights (2.5 GB)
  • shirt_male_weights (2.5 GB)
  • This link has all the weights listed above as well as the following:
    • pant_female_weights
    • pant_male_weights
    • short-pant_female_weights
    • short-pant_male_weights
    • skirt_female_weights
• Set output path in run_tailornet.py and run it to predict garments on some random inputs. You can play with different inputs. You can also run inference on motion sequence data.
• To visualize predicted garment using blender, run python run_tailornet.py render. (Blender 2.79 needs to be installed.)

Training TailorNet yourself

• Set global variables in global_var.py, especially LOG_DIR where training logs will be stored.
• Set config variables like gender and garment class in trainer/base_trainer.py (or pass them via command line) and run python trainer/base_trainer.py to train TailorNet MLP baseline.
• Similarly, run python trainer/lf_trainer.py to train low frequency predictor and trainer/ss2g_trainer.py to train shape-style-to-garment(in canonical pose) model.
• Run python trainer/hf_trainer.py --shape_style <shape1>_<style1> <shape2>_<style2> ... to train pivot high frequency predictors for pivots <shape1>_<style1>, <shape2>_<style2>, and so on. See DATA_DIR/<garment_class>_<gender>/pivots.txt to know available pivots.
• Use models.tailornet_model.TailorNetModel with appropriate logdir arguments to do prediction.

Inference Time

In the paper, we report inference time to be 1-2 ms per frame(depending upon garment) which is averaged inference time over the batch of 21 samples(20-40 ms per batch). Apologies for the ambiguity. Running each sample separately takes almost same time as batch - around 20 ms per frame for all garments. However, note that TailorNet has 21 independent MLPs, so we believe that faster inference time is possible if MLPs are configured to run in parallel on GPU cores.

Misc

• See ./models/skirt_model.md for the explanation of skirt garment model.
• Thanks to Bharat for many fruitful discussions and for smpl_lib library taken from his MultiGarmentNet repo's lib folder.
• Thanks to Garvita for helping out during the onerous procedure of data generation.
