hpnet's Introduction

HPNet

This repository contains the PyTorch implementation of paper: HPNet: Deep Primitive Segmentation Using Hybrid Representations.

Installation

The main experiments are implemented on pytorch 1.7.0, tensorflow 1.15.0. Please install the dependancy packages using pip install -r requirements.txt.

Dataset

ABCParts Dataset

ABCParts Dataset is made by ParseNet. Please download our preprocessed dataset here(69G) and put it under data/ABC folder. We add primitive parameters of each object in this dataset.

We also provide the preprocessing scripts under utils folder. To process by yourself, please run

cd utils
python process_abc.py --data_path=/path/to/parsenet-codebase/data/shapes --save_path=/path/to/saved/dir

Usage

To train our model on ABC dataset: run

python train.py --data_path=./path/to/dataset`

To evaluate our model on ABC dataset: run

python train.py --eval --checkpoint_path=./path/to/pretrained/model --val_skip=100

on the subset of test dataset. To test on the full dataset, simply set val_skip=1.

pretrained models

We provide pre-trained model on ABC Dataset here. This should generate the result reported in the paper.
