DGCNN-Pytorch
A Re-Implement of Dynamic Graph CNN for Point-Cloud Classification and Segmentation
Dynamic Graph CNN for Learning on Point Clouds
We propose a new neural network module dubbed EdgeConv suitable for CNN-based high-level tasks on point clouds including classification and segmentation. EdgeConv is differentiable and can be plugged into existing architectures.
Overview
DGCNN-Pytorch
is my personal re-implementation of Dynamic Graph CNN.
Run
Point-Cloud Data Preparations
There is two ways to convert ModelNet40 PLY or OFF file to Point-Cloud.
-
Use
h5_dataloader.py
download andload modelnet40_ply_hdf5_2048
files -
Custom down-sampling points from mesh. Download Modelnet40 off file, and unzip it in
Data/ModelNet40
RunSampler
withtest = 0
andtest = 1
, and sampled point-cloud file will save inModelNet40_
Next runpointcloud_dataloader
to convert*.points
to h5 file.Data\ModelNet40_
folder will createModelNet40_test.h5
andModelNet40_train.h5
Train
Train model: Run train
to train your model. Now is PointNet, next will update to pointnet and DGCNN.
To-Do
Next few days, will upload DGCNN model.
