Plug-and-Play Priors for Bright Field Electron Tomography and Sparse Interpolation
Suhas Sreehari, S. V. Venkatakrishnan, Brendt Wohlberg +3
Many material and biological samples in scientific imaging are characterized by non-local repeating structures. These are studied using scanning electron microscopy and electron to…
Statistical Estimation and Clustering of Group-invariant Orientation Parameters
Yu-Hui Chen, Dennis Wei, Gregory Newstadt +3
We treat the problem of estimation of orientation parameters whose values are invariant to transformations from a spherical symmetry group. Previous work has shown that any such gr…
A Dictionary Approach to EBSD Indexing
Yu-Hui Chen, Se Un Park, Dennis Wei +5
We propose a framework for indexing of grain and sub-grain structures in electron backscatter diffraction (EBSD) images of polycrystalline materials. The framework is based on a pr…
Coercive Region-level Registration for Multi-modal Images
Yu-Hui Chen, Dennis Wei, Gregory Newstadt +2
We propose a coercive approach to simultaneously register and segment multi-modal images which share similar spatial structure. Registration is done at the region level to facilita…
