Projection-free Graph-based Classifier Learning using Gershgorin Disc Perfect Alignment
Cheng Yang, Gene Cheung, Guangtao Zhai
In semi-supervised graph-based binary classifier learning, a subset of known labels are used to infer unknown labels, assuming that the label signal is smo…
Identification of deep breath while moving forward based on multiple body regions and graph signal analysis
Yunlu Wang, Cheng Yang, Menghan Hu +4
This paper presents an unobtrusive solution that can automatically identify deep breath when a person is walking past the global depth camera. Existing non-contact breath assessmen…
Joint Demosaicking / Rectification of Fisheye Camera Images using Multi-color Graph Laplacian Regularization
Fengbo Lan, Cheng Yang, Gene Cheung +1
To compose a 360 image from a rig with multiple fisheye cameras, a conventional processing pipeline first performs demosaicking on each fisheye camera's Bayer-patterned grid, then…
Signed Graph Metric Learning via Gershgorin Disc Perfect Alignment
Cheng Yang, Gene Cheung, Wei Hu
Given a convex and differentiable objective $Q(\M)$ for a real symmetric matrix $\M$ in the positive definite (PD) cone -- used to compute Mahalanobis distances -- we propose a fas…
Avalon: Building an Operating System for Robotcenter
Yuan Xu, Zhiyuan Yan, Sa Wang +3
This paper envisions a scenario that hundreds of heterogeneous robots form a robotcenter which can be shared by multiple users and used like a single powerful robot to perform comp…
Fast 3D Point Cloud Denoising via Bipartite Graph Approximation & Total Variation
Chinthaka Dinesh, Gene Cheung, Ivan V. Bajic +1
Acquired 3D point cloud data, whether from active sensors directly or from stereo-matching algorithms indirectly, typically contain non-negligible noise. To address the point cloud…
