Buried Fiber-Optic Geolocalization with Distributed Acoustic Sensing
Khen Cohen, Natanel Nissan, Ofir Nissan +1
We present a scalable method for geolocalizing buried fiber-optic cables using Distributed Acoustic Sensing (DAS) and traffic-induced quasi-static seismic signals. Assuming access…
SONAR: Spectral-Contrastive Audio Residuals for Generalizable Deepfake Detection
Ido Nitzan Hidekel, Gal lifshitz, Khen Cohen +1
Deepfake (DF) audio detectors still struggle to generalize to out of distribution inputs. A central reason is spectral bias, the tendency of neural networks to learn low-frequency…
Training a Distributed Acoustic Sensing Traffic Monitoring Network With Video Inputs
Khen Cohen, Liav Hen, Ariel Lellouch
Distributed Acoustic Sensing (DAS) has emerged as a promising tool for real-time traffic monitoring in densely populated areas. In this paper, we present a novel concept that integ…
Multispectral Imaging with Fresnel Lens
Khen Cohen, Tuval Kay
This paper presents a Multispectral imaging (MSI) approach that combines the use of a diffractive optical element, and a deep learning algorithm for spectral reconstruction. Tradit…
Person Recognition using Facial Micro-Expressions with Deep Learning
Tuval Kay, Yuval Ringel, Khen Cohen +2
This study investigates the efficacy of facial micro-expressions as a soft biometric for enhancing person recognition, aiming to broaden the understanding of the subject and its po…
Temporal Super-Resolution using Multi-Channel Illumination Source
Khen Cohen, Dan Raviv, David Mendlovic
While sensing in high temporal resolution is necessary for wide range of application, it is still limited nowadays due to cameras sampling rate. In this work we try to increase the…
Illumination-Based Color Reconstruction for the Dynamic Vision Sensor
Khen Cohen, Omer Hershko, Homer Levy +2
This work demonstrates a novel, state of the art method to reconstruct colored images via the Dynamic Vision Sensor (DVS). The DVS is an image sensor that indicates only a binary c…
