Self-Point-Flow: Self-Supervised Scene Flow Estimation from Point Clouds with Optimal Transport and Random Walk
Ruibo Li, Guosheng Lin, Lihua Xie
Due to the scarcity of annotated scene flow data, self-supervised scene flow learning in point clouds has attracted increasing attention. In the self-supervised manner, establishin…
Online Visual Place Recognition via Saliency Re-identification
Han Wang, Chen Wang, Lihua Xie
As an essential component of visual simultaneous localization and mapping (SLAM), place recognition is crucial for robot navigation and autonomous driving. Existing methods often f…
Multi-Path Region Mining For Weakly Supervised 3D Semantic Segmentation on Point Clouds
Jiacheng Wei, Guosheng Lin, Kim-Hui Yap +2
Point clouds provide intrinsic geometric information and surface context for scene understanding. Existing methods for point cloud segmentation require a large amount of fully labe…
Fast Loop Closure Detection via Binary Content
Han Wang, Juncheng Li, Maopeng Ran +1
Loop closure detection plays an important role in reducing localization drift in Simultaneous Localization And Mapping (SLAM). It aims to find repetitive scenes from historical dat…
Kervolutional Neural Networks
Chen Wang, Jianfei Yang, Lihua Xie +1
Convolutional neural networks (CNNs) have enabled the state-of-the-art performance in many computer vision tasks. However, little effort has been devoted to establishing convolutio…
Kernel Cross-Correlator
Chen Wang, Le Zhang, Lihua Xie +1
Cross-correlator plays a significant role in many visual perception tasks, such as object detection and tracking. Beyond the linear cross-correlator, this paper proposes a kernel c…
Sparse MRI for motion correction
Zai Yang, Cishen Zhang, Lihua Xie
MR image sparsity/compressibility has been widely exploited for imaging acceleration with the development of compressed sensing. A sparsity-based approach to rigid-body motion corr…
