WebOur work can be viewed as an extension of PointNet [20] with added hierarchical structure. We first review PointNet (Sec. 3.1) and then introduce a basic extension of PointNet with hierarchical structure (Sec. 3.2). Finally, we propose our PointNet++ that is able to robustly learn features even in non-uniformly sampled point sets (Sec. 3.3). 2

WebPointNet [23] is a pioneer of this type of method, which uses permutation-invariant operators (such as shared-weight MLPs and pooling layers) to aggregate features of a set of points. PointNet++ [24] further explores this idea by intro-ducing a hierarchical spatial structure that can capture the WebPOINT INTERNET.
