WebAbstract Data Type: ADT may be defined as a set of data values and associated operations that are precisely specified independent of any particular implementation. Thus an Abstract Data Type is an organized collection of information and a set of operations used to manage that information. The set of operations defines the interface of the ADT. Webby this, we propose a novel pillar set abstraction (PSA) which implements the pillar-based grouping operation in the SA of PointNet++ [20]. Speciﬁcally, we use the FPS algorithm to sample key points and PointNet to learn the features in the PSA layer. After the FPS, we employ a pillar-based grouping operation to partition points into several ...
