Ptychographic Image Reconstruction from Limited Data via Score-Based Diffusion Models with Physics-Guidance
Refik Mert Cam, Junjing Deng, Rajkumar Kettimuthu +2
Ptychography is a data-intensive computational imaging technique that achieves high spatial resolution over large fields of view. The technique involves scanning a coherent beam ac…
Masked Sinogram Model with Transformer for ill-Posed Computed Tomography Reconstruction: a Preliminary Study
Zhengchun Liu, Rajkumar Kettimuthu, Ian Foster
Computed Tomography (CT) is an imaging technique where information about an object are collected at different angles (called projections or scans). Then the cross-sectional image s…
BraggNN: Fast X-ray Bragg Peak Analysis Using Deep Learning
Zhengchun Liu, Hemant Sharma, Jun-Sang Park +5
X-ray diffraction based microscopy techniques such as High Energy Diffraction Microscopy rely on knowledge of the position of diffraction peaks with high precision. These positions…
Scientific Image Restoration Anywhere
Vibhatha Abeykoon, Zhengchun Liu, Rajkumar Kettimuthu +2
The use of deep learning models within scientific experimental facilities frequently requires low-latency inference, so that, for example, quality control operations can be perform…
Deep Learning Accelerated Light Source Experiments
Zhengchun Liu, Tekin Bicer, Rajkumar Kettimuthu +1
Experimental protocols at synchrotron light sources typically process and validate data only after an experiment has completed, which can lead to undetected errors and cannot enabl…
