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…
