Loss Distillation via Gradient Matching for Point Cloud Completion with Weighted Chamfer Distance

IROS 2024poster

3D point clouds enhanced the robot’s ability to perceive the geometrical information of the environments, making it possible for many downstream tasks such as grasp pose detection and scene understanding. The performance of these tasks, though, heavily relies on the quality of data input, as incompl…

Hyperbolic Chamfer Distance for Point Cloud Completion

ICCV 2023poster

Chamfer distance (CD) is a standard metric to measure the shape dissimilarity between point clouds in point cloud completion, as well as a loss function for (deep) learning. However, it is well known that CD is vulnerable to outliers, leading to the drift towards suboptimal models. In contrast to th…

InfoCD: A Contrastive Chamfer Distance Loss for Point Cloud Completion

NeurIPS 2023poster

A point cloud is a discrete set of data points sampled from a 3D geometric surface. Chamfer distance (CD) is a popular metric and training loss to measure the distances between point clouds, but also well known to be sensitive to outliers. To address this issue, in this paper we propose InfoCD, a no…

EPAR: An Efficient and Privacy-Aware Augmented Reality Framework for Indoor Location-Based Services

IROS 2022poster

Augmented reality (AR) defines a new information-delivery paradigm by overlaying computer-generated information on the perception of the real world. AR-integrated robot has become an appealing concept in terms of enhanced human-robot interaction. Despite intensive research on AR, existing indoor loc…
