A new research paper explores the effectiveness of test-time refinement strategies for LiDAR semantic scene completion. The study compares one-shot predictors, wider one-shot predictors, and iterative refinement systems, finding that iterative approaches offer a modest improvement in mean Intersection over Union (mIoU) for specific geometric conditions like coherent gaps. However, for broader thinning or additive clutter, training coverage and different robustness mechanisms prove more effective. The iterative system also incurs higher computational costs in terms of time and memory. AI
