Luka Doncic came through with yet another triple-double. About the only thing he didn't do was keep his record streak going. Doncic had 27 points, recording another triple-double -- but doing so without scoring 30 for the first time in seven games -- and the Dallas Mavericks rolled over the Chicago Bulls 127-92 on Monday night.. Doncic finished with 14 assists and 12 rebounds but exited the ...

Computer Science, Engineering. TLDR. A novel Point 4D Transformer (P4Transformer) network to model raw point cloud videos that combines a point 4D convolution to embed the spatio-temporal local structures presented in a point cloud video and a transformer to capture the appearance and motion information across the entire video by performing ...

Point 4D Transformer Networks for Spatio-Temporal Modeling in Point Cloud Videos. Introduction. Point cloud videos exhibit irregularities and lack of order along the spatial dimension where points emerge inconsistently across different frames. To capture the dynamics in point cloud videos, point tracking is usually employed.

To overcome this problem, we propose 4K4D, a 4D point cloud representation that supports hardware rasterization and enables unprecedented rendering speed. Our representation is built on a 4D feature grid so that the points are naturally regularized and can be robustly optimized.

The per-point features of each 4D sequence are first extracted using the 4D backbone. Following that, an intra-primitive point transformer is used to extract low-level features. Point features can provide the most fine-grained information, enabling us to better perform dense prediction tasks.

In this paper, to avoid tracking points, we propose a novel Point 4D Transformer Network (P4Transformer) to model the spatio-temporal structure in raw point cloud videos. First, we develop a point 4D convolution to en-code the spatio-temporal local structures in a point cloud video.
