11th Int'l Symposium on Image and Signal Processing and Analysis (ISPA 2019)

23-25 September 2019, Dubrovnik, Croatia

Plenary Speaker: Professor André Kaup

Chair of Multimedia Communications and Signal Processing, Friedrich-Alexander University Erlangen-Nürnberg, Germany

Lecture title: Signal Processing for Next Generation Video Communication Systems

Abstract

Video recording, transmission, and playback are widespread features of modern electronic consumer devices such as smart phones, digital cameras, and networked television systems. Thereby, the demand on image resolution, visual quality, and video functionality is steadily increasing, in turn raising a number of new and interesting research issues. In this talk we will focus on some recent developments in the field of signal processing for next generation video communication systems. First we address ultra-wide angle fisheye lenses, as used in surveillance and automotive applications, which produce video data with characteristics that differ significantly from perspective pinhole cameras. We will show how including an appropriate projection function can considerably improve video compression as well as temporal frame interpolation. Next, we focus on energy efficiency of video coding systems, where we will explain how including a suitable energy model into the rate-distortion optimization of the encoder can substantially increase battery lifetime during video playback. Finally, we will introduce random sampling as a promising concept for efficient scalable reconstruction of visual data.

Plenary Speaker: Professor P. P. Vaidyanathan

Kiyo and Eiko Tomiyasu Professor of Electrical Engineering, California Institute of Technology, Pasadena, CA, USA

Lecture title: The math genius Ramanujan and Digital Signal Processing

Abstract

The great Indian mathematician Srinivasa Ramanujan introduced a summation in 1918, called the Ramanujan-sum. For many years this summation was used by mathematicians to prove important results in number theory. In recent years, some researchers have found applications of this sum in digital signal processing, especially in identifying periodic components of signals buried in noise. In our recent work we have generalized the Ramanujan-sum decomposition in several directions, and this has opened up some new theory as well as applications. Many beautiful properties are enjoyed by the new representations, thanks to the genius and vision of Ramanujan. In this talk we briefly talk about Ramanujan as a person and then give an overview of the new developments. Applications in the study of DNA and protein sequences will be presented among others.

He received the IEEE Gustav Robert Kirchhoff Award (an IEEE Technical Field Award) in 2016, for “Fundamental contributions to digital signal processing.” He was elected to the U.S. National Academy of Engineering in 2019.

Plenary Speaker: Professor Edoardo Provenzi

Institute of Mathematics, University of Bordeaux, France

Lecture title: Towards a new model for the space of perceived colors

Abstract

Resnikoff's model of the space of perceived colors P, proposed in 1974, introduced important insights about the geometrical structure of P that passed unnoticed for more than 40 years. In the first part of the presentation, I will recap Resnikoff's work by underlying the basic results that he obtained. In the second part, I will show some drawbacks of his theory and discuss how we can overcome them with the use of Jordan algebras. Finally, I will put the accent on the exigence of some new psycho-physical experiments needed to validate some mathematical hypotheses.

Biography

Edoardo Provenzi received a master in Theoretical Physics from the university of Milan in 2000 and a PhD in mathematics and applications from the university of Milan in 2004. After two post-docs in Italy and in Spain, he was hired as Associate Professor at Université Paris Descartes in 2014 and as a Full Professor at Université de Bordeaux in 2017. He has been working on variational models of color vision and processing, high dynamic range images and statistics of natural images. His main actual interest is in the quantum-relativistic geometric reformulation of colorimetry.
