Point Sampling Net: Revolutionizing Instance Segmentation in Point Cloud Data

open access: yesIEEE Access, 2023
Today, there is a great need for 3D instance segmentation, which has several uses in robotics and augmented reality. Unlike projective observations like 2D photographs, 3D models offer a metric reconstruction of the sceneries without occlusion or scale ambiguity of the environment.

Deep FusionNet for Point Cloud Semantic Segmentation [PDF]

open access: yes, 2020
Many point cloud segmentation methods rely on transferring irregular points into a voxel-based regular representation. Although voxel-based convolutions are useful for feature aggregation, they produce ambiguous or wrong predictions if a voxel contains points from different classes.

Point Cloud Structural Parts Extraction based on Segmentation Energy Minimization [PDF]

open access: yes, 2015
In this work we consider 3D point sets, which in a typical setting represent unorganized point clouds. Segmentation of these point sets requires first to single out structural components of the unknown surface discretely approximated by the point cloud ...

Indoor Scene Segmentation Model Using Three-Dimensional Point Cloud Based on Super Point Graph Network [PDF]

open access: yesJisuanji gongcheng, 2021
The samples of the existing current point cloud datasets are unbalanced, and PointNet can not effectively utilize the neighborhood information of the point cloud.To address the problem, a three-dimensional scene segmentation method using point cloud is ...

Meshing Genus-1 Point Clouds Using Discrete One-Forms [PDF]

open access: yes, 2006
We present an algorithm to mesh point clouds sampled from a closed manifold surface of genus 1. The method relies on a doubly periodic global parameterization of the point cloud to the plane, so no segmentation of the point cloud is required.

Deep Projective 3D Semantic Segmentation

open access: yes, 2017
Semantic segmentation of 3D point clouds is a challenging problem with numerous real-world applications. While deep learning has revolutionized the field of image semantic segmentation, its impact on point cloud data has been limited so far.

PUPS: Point Cloud Unified Panoptic Segmentation

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2023
Point cloud panoptic segmentation is a challenging task that seeks a holistic solution for both semantic and instance segmentation to predict groupings of coherent points. Previous approaches treat semantic and instance segmentation as surrogate tasks, and they either use clustering methods or bounding boxes to gather instance groupings with costly ...

Point cloud segmentation using hierarchical tree for architectural models

open access: yes, 2018
Recent developments in the 3D scanning technologies have made the generation of highly accurate 3D point clouds relatively easy but the segmentation of these point clouds remains a challenging area.

Extraction of main levels of a building from a large point cloud [PDF]

open access: yes, 2019
Horizontal levels are references entities, the base of man-made environments. Their creation is the first step for various applications including the BIM (Building Information Modelling).
