Lippmann Photography: Past, Present, and Future
Paolo Prandoni, Arnaud Latty, Adrien Guillaume Olivier Hoffet, Nicoletta Isaac
The purpose of this project was to bring to a wider public an almost forgotten technique for color photography, invented by Gabriel Lippmann in 1892 and rewarded with a Nobel prize in 1908. The project was born out of a longstanding cooperation between EPF ...
2023Non-Intrusive Speech Quality Assessment with Transfer Learning and Subject-specific Scaling
Milos Cernak, Paolo Prandoni, Natalia Nessler
In communication systems, it is crucial to estimate the perceived quality of audio and speech. The industrial standards for many years have been PESQ, 3QUEST, and POLQA, which are intrusive methods. This restricts the possibilities of using these metrics i ...
ISCA-INT SPEECH COMMUNICATION ASSOC2021Teaching Practical DSP with Off-the-Shelf Hardware and Free Software
Paolo Prandoni, Eric Bezzam, Adrien Guillaume Olivier Hoffet
In this paper we describe our approach to teaching applied digital signal processing (DSP) using freely-available software and inexpensive off-the-shelf hardware components. The pedagogical framework is built around simple real-time audio processing algori ...
IEEE2019VITRAIL : Acquisition, Modelling and Rendering of Stained Glass
Martin Vetterli, Paolo Prandoni, Loïc Arnaud Baboulaz, Niranjan Thanikachalam
Stained glass windows are designed to reveal their powerful artistry under diverse and time-varying lighting conditions; virtual relighting of stained glass, therefore represents an exceptional tool for the appreciation of this age old art form. However, a ...
Institute of Electrical and Electronics Engineers2016Analysis and Design of Large-scale Online Classes
Martin Vetterli, Paolo Prandoni, Tao-Chun Lee
Massive Open Online Courses (MOOCs) have become an emergent paradigm of large-scale knowledge distribution, have generated wide interest in the higher education community and are anticipated by many to bring impact to the future of higher education. In thi ...
2014Light Transport Matrix recovery for nearly planar objects
Martin Vetterli, Paolo Prandoni, Loïc Arnaud Baboulaz, Niranjan Thanikachalam
The light transport matrix has become a powerful tool for scene relighting, owing to the versatility of its representational power of various light transport phenomenon. We argue that scenes with an almost planar surface geometry, even with significant amo ...
SPIE2014Method, system and computer program for determining a reflectance distribution function of an object
Martin Vetterli, Paolo Prandoni, Loïc Arnaud Baboulaz
The invention refers to a method for analysing reflected light of an object. First a light angle distribution for a point of the object is determined. Then a plenoptic projector is controlled to illuminate the point of the object with the determined light ...
2014Light field panorama by a plenoptic camera
Martin Vetterli, Paolo Prandoni, Loïc Arnaud Baboulaz, Zhou Xue
Consumer-grade plenoptic camera Lytro draws a lot of interest from both academic and industrial world. However its low resolution in both spatial and angular domain prevents it from being used for fine and detailed light field acquisition. This paper propose ...
SPIE2013Guessing the fingerings from musical recordings
Paolo Prandoni, Arnaud Latty, Frederike Dümbgen
Synopsis: This project is about using musical recordings of string instruments to determine on which strings notes have been played. It includes the study of the spectral content of the recordings and the development of a robust classifica ...
2012Sensorcam: An Energy-Efficient Smart Wireless Camera for Environmental Monitoring
Martin Vetterli, Paolo Prandoni, Guillermo Barrenetxea Kobas, Zichong Chen
Reducing energy cost is crucial for energy-constrained smart wireless cameras. Existing platforms impose two main challenges: First, most commercial smart phones have a closed platform, which makes it impossible to manage low-level circuits. Since the samp ...
