Title: Acquisition, processing and display of High Dynamic Range Data in the Rendering Pipeline
Abstract: In this talk, I will give an overview on how to capture, process, and display HDR images inside a rendering pipeline; through recent works of my research. HDR datum are important because they are becoming available to consumers in an efficient and easy way. For example modern mobile phones (e.g. iPhone, Nexus, etc.) can shoot in HDR producing compelling pictures. HDR imaging is not only about having nice pictures, but it is about capturing real-world colors and luminance values without overexposed and underexposed pixels. This information is very valuable for better processing and increasing the realism in applications such as relighting.

Title: Human Mobility, Social Networks, and Economic Development
Abstract: Previous investigations have proposed the existence of a positive association between social relations and economic opportunities on an individual level. Based on the availability of new (big) data sources, it has recently become possible to empirically verify the persistence of this relationship on (i) a more general community level and (ii) within larger territories like, for instance, nations. In this paper we expand this line of research to the country of France. Based on widely gathered CDR data and the smallest possible census level data, we investigate the specificities of the relationship between social network diversity and several socio-economic data. In a second part, we challenge the idea that social network diversity is the best, let alone, the only structural associator of socio-economic development. We introduce metrics for individual mobility diversity based on the spatial traces of the CDR data and we evaluate their relationship with the same socio-economic indicators. Our findings show that individual mobility diversity prevails a stronger association with several socio-economic indicators compared to social network diversity. This challenges us to question the influence of social network diversity on economic development in a more multi-dimensional logic.

Title: Succinct Data Structures
Abstract: The last few years have seen an intensive research on the so-called succinct and compressed data structures. These data structures mimic the operations of their classical counterparts within a comparable time complexity by requiring much less space. This goal is achieved by carefully combining ideas born both in algorithmic and information theory fields. Even if this area of research is relatively new, a large fraction of classical data structures have their succinct counterparts, and, since most of them are also of practical interest, many authors are successfully applying their underlying ideas to solve problems in other, more applicative, fields of research. In this talk we will introduce this field of research by presenting succinct solutions to represent set of integers, set of points, graphs and strings together with some practical problems in which they play a central role.
