SpiRadar: Radar-Based Non-Contact Spirometry via Sparse Polynomial Framework
Yonathan Eder, Yhonatan Kvich, Naama Golan +6
Chronic respiratory diseases affect hundreds of millions of people worldwide, with spirometry serving as the gold standard for pulmonary function assessment. However, conventional…
Lattice Modulo Sampling
Yhonatan Kvich, Yonina C. Eldar
We propose a lattice-theoretic framework for modulo sampling of multidimensional bandlimited signals. Standard modulo analog-to-digital converters (ADCs) fold the signal component-…
Physics Informed Deep Unfolded Full Waveform Inversion for Edema Detection
Ruizhi Zhang, Yhonatan Kvich, Rui Guo +2
Edema is a potential indicator of underlying pathological changes. However, its low-contrast signature is often masked in conventional B-mode imaging by strong scatterers, making r…
Compressed BC-LISTA via Low-Rank Convolutional Decomposition
Han Wang, Yhonatan Kvich, Eduardo Pérez +2
We study Sparse Signal Recovery (SSR) methods for multichannel imaging with compressed {forward and backward} operators that preserve reconstruction accuracy. We propose a Compress…
