Alternating Direction Method of Multipliers for Negative Binomial Model with The Weighted Difference of Anisotropic and Isotropic Total Variation
Yu Lu, Kevin Bui, Roummel F. Marcia
In many applications such as medical imaging, the measurement data represent counts of photons hitting a detector. Such counts in low-photon settings are often modeled using a Pois…
Negative Binomial Matrix Completion
Yu Lu, Kevin Bui, Roummel F. Marcia
Matrix completion focuses on recovering missing or incomplete information in matrices. This problem arises in various applications, including image processing and network analysis.…
An Image Segmentation Model with Transformed Total Variation
Elisha Dayag, Kevin Bui, Fredrick Park +1
Based on transformed regularization, transformed total variation (TTV) has robust image recovery that is competitive with other nonconvex total variation (TV) regularizers…
PIVOT-Net: Heterogeneous Point-Voxel-Tree-based Framework for Point Cloud Compression
Jiahao Pang, Kevin Bui, Dong Tian
The universality of the point cloud format enables many 3D applications, making the compression of point clouds a critical phase in practice. Sampled as discrete 3D points, a point…
