Introduction
This repository contains the implementation of Kernel Point Convolution (KPConv) in PyTorch.
KPConv is also available in Tensorflow (original but older implementation)
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.
-
Object Classification: Instructions to train KP-CNN on an object classification task (Modelnet40).
-
Scene Segmentation: Instructions to train KP-FCNN on a scene segmentation task (S3DIS).
-
SLAM Segmentation: Instructions to train KP-FCNN on a slam segmentation task (SemanticKitti).
-
Pretrained models: We provide pretrained weights and instructions to load them.
-
Visualization scripts: For now only one visualization script has been implemented: the kernel deformations display.
TODO: Guide for these experiments
