Introduction

This repository contains the implementation of Kernel Point Convolution (KPConv) in PyTorch.

KPConv is also available in Tensorflow (original but older implementation).

Another implementation of KPConv is available in PyTorch-Points-3D

KPConv is a point convolution operator presented in our ICCV2019 paper (arXiv). If you find our work useful in your research, please consider citing:

Installation

This implementation has been tested on Ubuntu 18.04 and Windows 10. Details are provided in INSTALL.md.

Experiments

We provide scripts for three experiments: ModelNet40, S3DIS and SemanticKitti. The instructions to run these experiments are in the doc folder.
