Point clouds are essential in various fields like autonomous driving and robotics, demanding efficient downsampling methods. Traditional approaches lack adaptability to different task requirements. REPS introduces a reconstruction-based scoring strategy that evaluates point importance through reconstruction processes, ensuring preservation of structural features. The Global-Local Fusion Attention module integrates local and global features for high-quality reconstruction and sampling effects. Experimental results demonstrate superior performance across tasks.
