Code for "DPFM: Deep Partial Functional Maps" - 3DV 2021 (Oral)

overview

Installation

This implementation runs on python >= 3.7, use pip to install dependencies:

pip3 install -r requirements.txt

Download data & preprocessing

The data should be downloaded and placed in the data folder. Each data folder should have two subfolders: shapes which contains the 3D meshes, and maps which contains the point-to-point ground truth maps that are used for training.

The data will be automatically processed when the training script is executed.

The datasets used in our paper are provided the dataset repository.

Usage

To train DPFM model on the shrec 16 partial dataset, use the training script:

python3 train_shrec_partial.py --config shrec16_cuts
# OR
python3 train_shrec_partial.py --config shrec16_holes

To evaluate a trained model, use:

python3 eval_shrec_partial.py --config shrec16_cuts --model_path path/to/saved/model --predictions_name path/to/save/perdiction/file

We provide two pre-trained models on the shrec 16 partial dataset which are available in data/saved_models.

  • cp2p pre-trained model

    cp2p pre-trained model

    Hello, is there any chance you can release the pre-trained models on cp2p?

    There are the pre-trained models for shrec-cuts and shrec-holes, which is awesome!

    Also, can you release the ground truth maps for test set of cp2p? Your evaluation code needs them, and it would be great to have to compute the error on the test set.

    Thank you, Luca

  • Question about Shrec'16 Dataset

    Question about Shrec'16 Dataset

    Hi, Happy New Year!!! I have a question about the use of Shrec'16 Dataset.

    I download the Dataset here: https://www.dais.unive.it/~shrec2016/dataset.php There are three contents available for download, and I downloaded the first one: Partial datasets with ground truth correspondences (~200 shapes) Test code to load and show ground-truth maps between shapes The evaluation cuts (200 shapes) and holes (200 shapes) databases

    I don't know if I downloaded it correctly.

    When I unzip the downloaded file, I found it has three folders, "cuts", "holes", "null", and the label correspondence files is ".baryc_gt" as suffix.

    In the documentation I found the following description: Ground-truth is provided for each deformed shape as a ASCII file with baryc_gt (baryc_gt_sym for the symmetric ground-truth) extension. Each row contains the triangle index and the barycentric weight of the corresponding point of the relative shape in canonical pose.

    However, in the code implementation such as "shrec_partial_dataset.py", and the implementation of the "ShrecPartialDataset" class, i found the label correspondence, and the code about read ground truth file is something about the file which is ".map" as suffix, this is different from the label file in Shrec'16 I downloaded.

    My question is how do I convert files from '.baryc_gt' to '.map' ?

    Thank you for your reply and help, have a nice day~~~
