Stratified Transformer for 3D Point Cloud Segmentation [PDF]

open access: yesComputer Vision and Pattern Recognition, 2022
3D point cloud segmentation has made tremendous progress in recent years. Most current methods focus on aggregating local features, but fail to directly model long-range dependencies.

Point-M2AE: Multi-scale Masked Autoencoders for Hierarchical Point Cloud Pre-training [PDF]

open access: yesNeural Information Processing Systems, 2022
Masked Autoencoders (MAE) have shown great potentials in self-supervised pre-training for language and 2D image transformers. However, it still remains an open question on how to exploit masked autoencoding for learning 3D representations of irregular ...

Point-Bind & Point-LLM: Aligning Point Cloud with Multi-modality for 3D Understanding, Generation, and Instruction Following [PDF]

open access: yesarXiv.org, 2023
We introduce Point-Bind, a 3D multi-modality model aligning point clouds with 2D image, language, audio, and video. Guided by ImageBind, we construct a joint embedding space between 3D and multi-modalities, enabling many promising applications, e.g., any-

Separation and Micro Determination of Zinc(II) and Cadmium(II) in Food Samples Using Cloud Point Extraction method

open access: yesIraqi Journal of Science, 2023
    The cloud point extraction technique has become increasingly popular in recent years for trace metal separation and preconcentration. When heated to a specific temperature, cloud point extraction utilizes the property of nonionic surfactants in ...

REGTR: End-to-end Point Cloud Correspondences with Transformers [PDF]

open access: yesComputer Vision and Pattern Recognition, 2022
Despite recent success in incorporating learning into point cloud registration, many works focus on learning feature descriptors and continue to rely on nearest-neighbor feature matching and outlier filtering through RANSAC to obtain the final set of ...

Point-BERT: Pre-training 3D Point Cloud Transformers with Masked Point Modeling [PDF]

open access: yesComputer Vision and Pattern Recognition, 2021
We present Point-BERT, a new paradigm for learning Transformers to generalize the concept of BERT [8] to 3D point cloud. Inspired by BERT, we devise a Masked Point Modeling (MPM) task to pre-train point cloud Transformers. Specifically, we first divide a

VoxelNet: End-to-End Learning for Point Cloud Based 3D Object Detection [PDF]

open access: yes2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2017
Accurate detection of objects in 3D point clouds is a central problem in many applications, such as autonomous navigation, housekeeping robots, and augmented/virtual reality.

PoinTr: Diverse Point Cloud Completion with Geometry-Aware Transformers [PDF]

open access: yesIEEE International Conference on Computer Vision, 2021
Point clouds captured in real-world applications are of-ten incomplete due to the limited sensor resolution, single viewpoint, and occlusion. Therefore, recovering the complete point clouds from partial ones becomes an indispensable task in many ...

Georeferenced Point Clouds: A Survey of Features and Point Cloud Management [PDF]

open access: yesISPRS International Journal of Geo-Information, 2013
This paper presents a survey of georeferenced point clouds. Concentration is, on the one hand, put on features, which originate in the measurement process themselves, and features derived by processing the point cloud. On the other hand, approaches for the processing of georeferenced point clouds are reviewed.
