# PyTorch Point-cloud Earth-Mover-Distance (EMD) Implementation
|
|
|
|
|
|
|
|
|
|
## Dependency
|
|
|
|
|
|
|
|
|
|
The code has been tested on Ubuntu 16.04, PyTorch 1.1.0, CUDA 9.0.
|
|
|
|
|
|
|
|
|
|
## Usage
|
|
|
|
|
|
|
|
|
|
First compile using
|
|
|
|
|
|
|
|
|
|
python setup.py install
|
|
|
|
|
|
|
|
|
|
Then, copy the lib file out to the main directory,
|
|
|
|
|
|
|
|
|
|
cp build/lib.linux-x86_64-3.6/emd_cuda.cpython-36m-x86_64-linux-gnu.so .
|
|
|
|
|
|
|
|
|
|
Then, you can use it by simply
|
|
|
|
|
|
|
|
|
|
from emd import earth_mover_distance
|
|
|
|
|
d = earth_mover_distance(p1, p2, transpose=False) # p1: B x N1 x 3, p2: B x N2 x 3
|
|
|
|
|
|
|
|
|
|
Check `test_emd_loss.py` for example.

The cuda code is originally written by Haoqiang Fan. The PyTorch wrapper is written by Kaichun Mo. Also, Jiayuan Gu provided helps.
