Two-Level Structural Sparsity Regularization for Identifying Lattices and Defects in Noisy Images
Xin Li, Alex Belianinov, Ondrej Dyck +2
This paper presents a regularized regression model with a two-level structural sparsity penalty applied to locate individual atoms in a noisy scanning transmission electron microsc…
A Mixture of Linear-Linear Regression Models for Linear-Circular Regression
Ali Esmaieeli Sikaroudi, Chiwoo Park
We introduce a new approach to a linear-circular regression problem that relates multiple linear predictors to a circular response. We follow a modeling approach of a wrapped norma…
Robust Regression For Image Binarization Under Heavy Noises and Nonuniform Background
Garret Vo, Chiwoo Park
This paper presents a robust regression approach for image binarization under significant background variations and observation noises. The work is motivated by the need of identif…
Sparse Filtered SIRT for Electron Tomography
Chen Mu, Chiwoo Park
Electron tomographic reconstruction is a method for obtaining a three-dimensional image of a specimen with a series of two dimensional microscope images taken from different viewin…
Directional Statistics of Preferential Orientations of Two Shapes in Their Aggregate and Its Application to Study Preferential Attachment of Nanoparticles
Ali Esmaieeli Sikaroudi, David A. Welch, Taylor Woehl +4
Nanoscientists have long conjectured that adjacent nanoparticles aggregate with one another in certain preferential directions during a chemical synthesis of nanoparticles, which i…
