LenslessMic: Audio Encryption and Authentication via Lensless Computational Imaging
Petr Grinberg, Eric Bezzam, Paolo Prandoni +1
With society's increasing reliance on digital data sharing, the protection of sensitive information has become critical. Encryption serves as one of the privacy-preserving methods;…
Encryption and Authentication with a Lensless Camera Based on a Programmable Mask
Eric Bezzam, Martin Vetterli
Lensless cameras replace traditional optics with thin masks, leading to highly multiplexed measurements akin to encryption. However, static masks in conventional designs leave syst…
Towards Robust and Generalizable Lensless Imaging with Modular Learned Reconstruction
Eric Bezzam, Yohann Perron, Martin Vetterli
Lensless cameras disregard the conventional design that imaging should mimic the human eye. This is done by replacing the lens with a thin mask, and moving image formation to the d…
Let There Be Light: Robust Lensless Imaging Under External Illumination With Deep Learning
Eric Bezzam, Stefan Peters, Martin Vetterli
Lensless cameras relax the design constraints of traditional cameras by shifting image formation from analog optics to digital post-processing. While new camera designs and applica…
A Modular and Robust Physics-Based Approach for Lensless Image Reconstruction
Yohann Perron, Eric Bezzam, Martin Vetterli
In this paper, we present a modular approach for reconstructing lensless measurements. It consists of three components: a newly-proposed pre-processor, a physics-based camera inver…
Privacy-Enhancing Optical Embeddings for Lensless Classification
Eric Bezzam, Martin Vetterli, Matthieu Simeoni
Lensless imaging can provide visual privacy due to the highly multiplexed characteristic of its measurements. However, this alone is a weak form of security, as various adversarial…
LenslessPiCam: A Hardware and Software Platform for Lensless Computational Imaging with a Raspberry Pi
Eric Bezzam, Sepand Kashani, Martin Vetterli +1
Lensless imaging seeks to replace/remove the lens in a conventional imaging system. The earliest cameras were in fact lensless, relying on long exposure times to form images on the…
Learning rich optical embeddings for privacy-preserving lensless image classification
Eric Bezzam, Martin Vetterli, Matthieu Simeoni
By replacing the lens with a thin optical element, lensless imaging enables new applications and solutions beyond those supported by traditional camera design and post-processing,…
pyFFS: A Python Library for Fast Fourier Series Computation and Interpolation with GPU Acceleration
Eric Bezzam, Sepand Kashani, Paul Hurley +2
Fourier transforms are an often necessary component in many computational tasks, and can be computed efficiently through the fast Fourier transform (FFT) algorithm. However, many a…
A study on more realistic room simulation for far-field keyword spotting
Eric Bezzam, Robin Scheibler, Cyril Cadoux +1
We investigate the impact of more realistic room simulation for training far-field keyword spotting systems without fine-tuning on in-domain data. To this end, we study the impact…
Pyroomacoustics: A Python package for audio room simulations and array processing algorithms
Robin Scheibler, Eric Bezzam, Ivan Dokmanić
We present pyroomacoustics, a software package aimed at the rapid development and testing of audio array processing algorithms. The content of the package can be divided into three…
FRIDA: FRI-Based DOA Estimation for Arbitrary Array Layouts
Hanjie Pan, Robin Scheibler, Eric Bezzam +2
In this paper we present FRIDA---an algorithm for estimating directions of arrival of multiple wideband sound sources. FRIDA combines multi-band information coherently and achieves…
