Weighted Multi-projection: 3D Point Cloud Denoising with Estimated Tangent Planes
Chaojing Duan, Siheng Chen, Jelena Kovačević
As a collection of 3D points sampled from surfaces of objects, a 3D point cloud is widely used in robotics, autonomous driving and augmented reality. Due to the physical limitation…
The eigenstructures of real (skew) circulant matrices with some applications
Zhongyun Liu, Siheng Chen, Weijin Xu +1
The circulant matrices and skew-circulant matrices are two special classes of Toeplitz matrices and play vital roles in the computation of Toeplitz matrices. In this paper, we focu…
Multiresolution Representations for Piecewise-Smooth Signals on Graphs
Siheng Chen, Aarti Singh, Jelena Kovačević
What is a mathematically rigorous way to describe the taxi-pickup distribution in Manhattan, or the profile information in online social networks? A deep understanding of represent…
