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…
Deep Unfolded Approximate Message Passing for Quantitative Acoustic Microscopy Image Reconstruction
Odysseas Pappas, Jonathan Mamou, Adrian Basarab +2
Quantitative Acoustic Microscopy (QAM) is an imaging technology utilising high frequency ultrasound to produce quantitative two-dimensional (2D) maps of acoustical and mechanical p…
High-resolution Coastline Extraction in SAR Images via MISP-GGD Superpixel Segmentation
Odysseas Pappas, Nantheera Anantrasirichai, Byron Adams +1
High accuracy coastline/shoreline extraction from SAR imagery is a crucial step in a number of maritime and coastal monitoring applications. We present a method based on image segm…
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…
