Microwave Lymphedema Assessment Using Deep Learning with Contour Assisted Backprojection Open
We present a method for early detection of lymphatic fluid accumulation in\nlymphedema patients based on microwave imaging of the limb volume across an air\ngap. The proposed algorithm uses contour information of the imaged limb surface\nt…

Sparse Signal Models for Data Augmentation in Deep Learning ATR Open
Automatic target recognition (ATR) algorithms are used to classify a given synthetic aperture radar (SAR) image into one of the known target classes by using the information gleaned from a set of training images that are available for each…

DLT-based Regulatory Systems Dynamics Open
In this research, we examine the interplay between ‘actors’ and ‘agents’ in Distributed Ledger Technology (DLT) systems. We identify regulatory interactions between off-chain agents setting the rules, as well as on-chain code as actors reg…

MrSARP: A Hierarchical Deep Generative Prior for SAR Image Super-resolution Open
Generative models learned from training using deep learning methods can be used as priors in inverse under-determined inverse problems, including imaging from sparse set of measurements. In this paper, we present a novel hierarchical deep-…

An Examination of the Feasibility of Detecting Cocaine Use Using Smartwatches Open
As digital technology increasingly informs clinical trials, novel ways to collect study data in the natural field setting have the potential to enhance the richness of research data. Cocaine use in clinical trials is usually collected via …

High Resolution Radar Sensing with Compressive Illumination Open
We present a compressive radar design that combines multitone linear frequency modulated (LFM) waveforms in the transmitter with a classical stretch processor and sub-Nyquist sampling in the receiver. The proposed compressive illumination …

Compressing bistatic SAR target signatures with sparse‐limited persistence scattering models Open
Here, the authors study the modelling of bistatic synthetic aperture radar (SAR) target signatures. They focus on building concise models inspired by physical phenomenology that explain target reflectivity over a wide range of bistatic ang…
