PHYSICS-INFORMED ANOMALY DETECTION OF TERRAIN MATERIAL CHANGE IN RADAR IMAGERY

ICASSP 2026poster

In this paper we consider physics-informed detection of terrain material change in radar imagery (e.g., shifts in permittivity, roughness or moisture). We propose a lightweight electromagnetic (EM) forward model to simulate bi-temporal single-look complex (SLC) images from labelled material maps. On…

Time-Varying Delay Estimation Using Common Local All-Pass Filters with Application to Surface Electromyography

ICASSP 2018accepted

Estimation of conduction velocity (CV) is an important task in the analysis of surface electromyography (sEMG). The problem can be framed as estimation of a time-varying delay (TVD) between electrode recordings. In this paper we present an algorithm which incorporates information from multiple elect…

Fuzzy entropy based nonnegative matrix factorization for muscle synergy extraction

ICASSP 2016accepted

The concept of muscle synergies has proven to be an effective method for representing patterns of muscle activation. The number of degrees of freedom to be controlled are reduced while also providing a flexible platform for producing detailed movements using synergies as building blocks. It has prev…
