WebFarthest point sampling is a greedy algorithm that samples from a point cloud data iteratively. It starts from a random single sample of point. In each iteration, it samples … WebClassic sampling approaches, such as farthest point sampling (FPS), do not consider the downstream task. A recent work showed that learning a task-specific sampling can improve results significantly. However, the proposed technique did not deal with the non-differentiability of the sampling operation and offered a workaround instead.
