A Multimodal Approach for Fluid Overload Prediction: Integrating Lung Ultrasound and Clinical Data

Tianqi Yang, Nantheera Anantrasirichai, Oktay Karakuş +2

Managing fluid balance in dialysis patients is crucial, as improper management can lead to severe complications. In this paper, we propose a multimodal approach that integrates vis…

Sparse InSAR Data 3D Inpainting for Ground Deformation Detection Along the Rail Corridor

Odysseas Pappas, Juliet Biggs, David Bull +2

Monitoring of ground movement close to the rail corridor, such as that associated with landslips caused by ground subsidence and/or uplift, is of great interest for the detection a…

Sparse regularization with a non-convex penalty for SAR imaging and autofocusing

Zi-Yao Zhang, Odysseas Pappas, Igor G. Rizaev +1

In this paper, SAR image reconstruction with joint phase error estimation (autofocusing) is formulated as an inverse problem. An optimization model utilising a sparsity-enforcing C…

SAR Image Autofocusing using Wirtinger calculus and Cauchy regularization

Zi-Yao Zhang, Odysseas Pappas, Alin Achim

In this paper, an optimization model using Cauchy regularization is proposed for simultaneous SAR image reconstruction and autofocusing. A coordinate descent framework in which the…
