Revealing Information by Averaging

Sabine Süsstrunk, Roger Hersch, Mahmut Sami Arpa

We present a method for hiding images in synthetic videos and reveal them by temporal averaging. The main challenge is to develop a visual masking method that hides the input image both spatially and temporally. Our masking approach consists of temporal an ...

A Time-Based, Digitally Intensive Circuit and System Architecture for Wireless Neural Recording with High Dynamic Range

Alexandre Schmid, Chen Cao, Wen-Yang Hsu

A new type of wireless neural recording front-end with PWM modulation and VCO-based ADC is proposed. The target signal is first encoded into binary levels with varying pulse width by PWM modulation, which intrinsically has much higher dynamic range compare ...

Color Changing Prints on a Metallic Substrate

Petar Pjanic

Printing on a flat metallic substrate has gained popularity in recent years. The reflection of light on a specularly reflecting metallic substrate differs strongly from the reflection of light on a diffusely reflecting medium such as paper. Direct prints o ...

Rating the performance of a Brillouin distributed fiber sensor

Luc Thévenaz, Marcelo Alfonso Soto Hernandez

The effect of the characteristics of a generic distributed fiber sensor based on stimulated Brillouin scattering on the amplitude of the response is analyzed and a relation between the measurement noise on the time traces and the error on the determination ...

Distributed Brillouin sensing with sub-meter spatial resolution: modeling and processing

Luc Thévenaz, Stella Foaleng Mafang

A general analytic solution for Brillouin distributed sensing in optical fibers with sub-meter spatial resolution is obtained by solving the acoustical-optical coupled wave equations by a perturbation method. The Brillouin interaction of a triad of square ...
