MiniChallenge in 2020 NPM3D course

The data layout is:

data/MiniChallenge
- training
- test

The 0 label corresponds to Unclassified data points in the point clouds.

Score

The prevous' year best score is 63.32

PointNet

We use this implementation of PointNet++ in PyTorch: https://github.com/erikwijmans/Pointnet2_PyTorch

GCO

We use "". Grab the code:

wget http://mouse.cs.uwaterloo.ca/code/gco-v3.0.zip

We use CMake as a build system for the C++ code. Build the code:

mkdir build/
cd build/
cmake ../gco
make

You can then check that the example file compiles:

./build/Main
