SenseAI: Real-Time Inpainting for Electron Microscopy

no code implementations25 Nov 2023 Jack Wells, Amirafshar Moshtaghpour, Daniel Nicholls, Alex W. Robinson, Yalin Zheng, Jony Castagna, Nigel D. Browning

Despite their proven success and broad applicability to Electron Microscopy (EM) data, joint dictionary-learning and sparse-coding based inpainting algorithms have so far remained impractical for real-time usage with an Electron Microscope.

Subsampling Methods for Fast Electron Backscattered Diffraction Analysis

no code implementations17 Jul 2023 Zoë Broad, Daniel Nicholls, Jack Wells, Alex W. Robinson, Amirafshar Moshtaghpour, Robert Masters, Louise Hughes, Nigel D. Browning

Despite advancements in electron backscatter diffraction (EBSD) detector speeds, the acquisition rates of 4-Dimensional (4D) EBSD data, i. e., a collection of 2-dimensional (2D) diffraction maps for every position of a convergent electron probe on the sample, is limited by the capacity of the detector.

Compressive Scanning Transmission Electron Microscopy

no code implementations22 Dec 2021 Daniel Nicholls, Alex Robinson, Jack Wells, Amirafshar Moshtaghpour, Mounib Bahri, Angus Kirkland, Nigel Browning

We support the proposed method by applying a series of masks to fully-sampled STEM data to simulate the expectation of real CS-STEM.

We discuss key aspects to realize this endeavor, namely (i) the design and exploitation of scalable and computationally efficient AI algorithms for Multi-Messenger Astrophysics; (ii) cyberinfrastructure requirements to numerically simulate astrophysical sources, and to process and interpret Multi-Messenger Astrophysics data; (iii) management of gravitational wave detections and triggers to enable electromagnetic and astro-particle follow-ups; (iv) a vision to harness future developments of machine and deep learning and cyberinfrastructure resources to cope with the scale of discovery in the Big Data Era; (v) and the need to build a community that brings domain experts together with data scientists on equal footing to maximize and accelerate discovery in the nascent field of Multi-Messenger Astrophysics.

Automatic structural parcellation of mouse brain MRI using multi-atlas label fusion

1 code implementation27 Jan 2014 Da Ma, Manuel J. Cardoso, Marc Modat, Nick Powell, Jack Wells, Holly Holmes, Frances Wiseman, Victor Tybulewicz, Elizabeth Fisher, Mark F. Lythgoe, Sébastien Ourselin

The segmentation accuracy of the multi-atlas framework was evaluated using publicly available mouse brain atlas databases with pre-segmented manually labelled anatomical structures as the gold standard, and optimised parameters were obtained for the STEPS algorithm in the label fusion to achieve the best segmentation accuracy.
