      abstract = {This paper introduces BOLT (Bilateral filtering and Octree Lightweight Technique), a novel, fast, and parameter-free method for up-sampling point clouds. We leverage the structural efficiency of the octree data structure and detail-preserving properties of the bilateral filter to achieve a fast and parameter-free sampling method. Unlike the current state-of-the-art techniques, BOLT does not require any parameters, deep learning, fine-tuning, or any type of training, making it a suitable candidate for real-time applications. BOLT understands the underlying structure of the point cloud by dividing the point cloud into a hierarchical octree structure. Empty children are filled in the octree, and outliers are smoothed using a bilateral filter.},
