MedPointS-CPL

This is the medical point cloud completion dataset from MedPointS, as presented in the paper "Hierarchical Feature Learning for Medical Point Clouds via State Space Model".

In this dataset, partial is the partial point cloud, 'target' is the target point cloud, and label is the class label.

Each point cloud has been normalized and sub-sampled to 2048 points. The correspondence between class names and labels is listed as follows (the label value plus 1 is the actual key of following map):

coarse_label_to_organ = {1: 'adrenalgland',
    2: 'aorta',
    3: 'autochthon',
    4: 'bladder',
    5: 'brain',

Sample Usage

To train and evaluate models for point cloud completion using the Flemme framework, you can use the following commands. Note that you may need to adjust /path/to/project/flemme/ to your local Flemme installation path.

## completion
train_flemme --config /path/to/project/flemme/resources/pcd/medpoints/cpl/train_pointmamba2knn_cpl.yaml
test_flemme --config /path/to/project/flemme/resources/pcd/medpoints/cpl/test_pointmamba2knn_cpl.yaml
