4D Spatio-Temporal ConvNets: Minkowski Convolutional Neural Networks

CVPR 2019 StanfordVL/MinkowskiEngine

To overcome challenges in the 4D space, we propose the hybrid kernel, a special case of the generalized sparse convolution, and the trilateral-stationary conditional random field that enforces spatio-temporal consistency in the 7D space-time-chroma space.

DeepGCNs: Can GCNs Go as Deep as CNNs?

ICCV 2019 2019 lightaime/deep_gcns

Finally, we use these new concepts to build a very deep 56-layer GCN, and show how it significantly boosts performance (+3. 7% mIoU over state-of-the-art) in the task of point cloud semantic segmentation.

RandLA-Net: Efficient Semantic Segmentation of Large-Scale Point Clouds

25 Nov 2019QingyongHu/RandLA-Net

We study the problem of efficient semantic segmentation for large-scale 3D point clouds.

The state of the art in kidney and kidney tumor segmentation in contrast-enhanced CT imaging: Results of the KiTS19 Challenge

2 Dec 2019neheller/kits19

The 2019 Kidney and Kidney Tumor Segmentation challenge (KiTS19) was a competition held in conjunction with the 2019 International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI) which sought to address these issues and stimulate progress on this automatic segmentation problem.

Associatively Segmenting Instances and Semantics in Point Clouds

CVPR 2019 WXinlong/ASIS

A 3D point cloud describes the real scene precisely and intuitively. To date how to segment diversified elements in such an informative 3D scene is rarely discussed.

SemanticKITTI: A Dataset for Semantic Scene Understanding of LiDAR Sequences

ICCV 2019 PRBonn/semantic-kitti-api

Despite the relevance of semantic scene understanding for this application, there is a lack of a large dataset for this task which is based on an automotive LiDAR.
