Fast Attention-Based Simplification of LiDAR Point Clouds for Object Detection and Classification

ArXi:2603.07593v1 Announce Type: new LiDAR point clouds are widely used in autonomous driving and consist of large numbers of 3D points captured at high frequency to represent surrounding objects such as vehicles, pedestrians, and traffic signs. While this dense data enables accurate perception, it also increases computational cost and power consumption, which can limit real-time deployment. Existing point cloud sampling methods typically face a trade-off: very fast approaches tend to reduce accuracy, while accurate methods are computationally expensive.
