Autonomous Polycrystalline Material Decomposition for Hyperspectral Neutron Tomography

no code implementations27 Feb 2023 Mohammad Samin Nur Chowdhury, Diyu Yang, Shimin Tang, Singanallur V. Venkatakrishnan, Hassina Z. Bilheux, Gregery T. Buzzard, Charles A. Bouman

The algorithm estimates the linear attenuation coefficient spectra from the measured radiographs and then uses these spectra to perform polycrystalline material decomposition and reconstructs 3D material volumes to localize materials in the spatial domain.

An Edge Alignment-based Orientation Selection Method for Neutron Tomography

no code implementations1 Dec 2022 Diyu Yang, Shimin Tang, Singanallur V. Venkatakrishnan, Mohammad S. N. Chowdhury, Yuxuan Zhang, Hassina Z. Bilheux, Gregery T. Buzzard, Charles A. Bouman

Neutron computed tomography (nCT) is a 3D characterization technique used to image the internal morphology or chemical composition of samples in biology and materials sciences.

Multi-Pose Fusion for Sparse-View CT Reconstruction Using Consensus Equilibrium

no code implementations15 Sep 2022 Diyu Yang, Craig A. J. Kemp, Gregery T. Buzzard, Charles A. Bouman

In this paper, we present Multi-Pose Fusion, a novel algorithm that performs a joint tomographic reconstruction from CT scans acquired from multiple poses of a single object, where each pose has a distinct rotation axis.

Ensemble Wrapper Subsampling for Deep Modulation Classification

1 code implementation10 May 2020 Sharan Ramjee, Shengtai Ju, Diyu Yang, Xiaoyu Liu, Aly El Gamal, Yonina C. Eldar

Subsampling of received wireless signals is important for relaxing hardware requirements as well as the computational cost of signal processing algorithms that rely on the output samples.
