“Walter was first my teacher at University of Florence and then he hired me for a programming job. In both the occasions he was a great guide to understand problems I had to deal with. He's very clear-minded and his explanations are worth than many readings. He also has a deep focus on multimedia related topics.”
About
I graduated with a degree in software engineering, and later a PhD, from the University of Florence - Italy. My research fields were computer vision and pattern recognition. I had the opportunity to work with two great research groups: the MICC lab at Univ. Florence (led by Prof. Alberto Del Bimbo), and - for a short period - the IVC lab at Boston University (led by Prof. Stan Sclaroff). My thesis presented techniques and algorithms applied to the automatic extraction of analytics from sport and urban videos. Some of these results appeared in well respected peer reviewed journals and conference proceedings (see the detailed list below).
In 2007 I co-founded Magenta (www.magentalab.it), a company that designs and builds software solutions tailored to specific customer requirements. We have specialised in multiple types of applications (enterprise, mobile, embedded) and sectors (transportation, safety, tourism, multimedia).
We are also very active in innovation and R&D. This reflects in my current role, which is to work on grants and research proposals. I have co-written, participated in and coordinated, projects funded by various ICT programmes, such as H2020, FP7, ERA-SME, Manunet, Crosstexnet, and others.
Recently, I've been using my technical skills for data-science projects, working my way through Python, Pandas, Databricks/Spark, and the like. An example is project AiRISE Inflow that is led by Thales with a consistent support of Magenta.

An integrated low-cost road traffic and air pollution monitoring platform for next citizen observatories
3rd Conference on Sustainable Urban Mobility, 3rd CSUM 2016, 26 27 May 2016, Volos, Greece
An integrated monitoring platform was developed for real-time monitoring of air pollution and traffic flows in urban areas. The air quality monitoring unit, integrating the Arduino open-source technology with low-cost and high-resolution sensors, collects concentrations of CO, NO2 and CO2. The traffic monitoring device, equipped with a camera sensor and a video analysis software, collects vehicles counts, speed and size. Air pollution and traffic readings are archived on a spatial data…

The air quality monitoring unit, integrating the Arduino open-source technology with low-cost and high-resolution sensors, collects concentrations of CO, NO2 and CO2. The traffic monitoring device, equipped with a camera sensor and a video analysis software, collects vehicles counts, speed and size. Air pollution and traffic readings are archived on a spatial data infrastructure composed of a central GeoDatabase, a GIS engine, and a web interface.
A platform s description and the results of its installation in Florence (Italy) are presented. -

Within our campaign, we will integrate our technology with an online platform for smart cities, in order to maximise the impact of the project in terms of affected users. We will also release the collected data in order to promote the diffusion of actual information through social media or mobile applications, that will help to steer the public toward better, more sustainable mobility modes.

SOLE-CUT will develop shared knowledge, practical know-how and a modern background of simulation methodologies and codes capable of designing and creating new families of high performing stone-cutting-machines. Innovative Shape Memory Alloys and Super-elastic materials will be considered for wire rope (substituting conventional steels) and technical, economic and ecological consistency of materials will be considered, thus producing innovative and green solutions for a more sustainable cutting process. SOLE-CUT proposes an innovative monitoring system, which applies machine vision technology for automatic surface inspection and fault / anomaly prevention in the cutting / carving process. SOLE-CUT groups 4 SMEs, from 3 Regions and 2 countries and integrates scientific and technological expertise with multi-year experience in stone manufacturing.

ORUSSI. Optimal Road sUrveillance System based on Scalable vIdeo

The growing mobility of people and goods has a very high societal cost in terms of traffic congestion and of fatalities and injured people every year. The management of a road network needs efficient ways for assessment at minimal costs.

The management of a road network needs efficient ways for assessment at minimal costs.
Road monitoring is a relevant part of road management, especially for safety, optimal traffic flow and for investigating new sustainable transport patterns. Current monitoring systems based on video lack of optimal usage of networks and are difficult to be extended efficiently.
The ORUSSI project focuses on road monitoring through a network of roadside sensors (mainly cameras) that can be dynamically deployed and added to the surveillance systems in an efficient way.
The main objective of the project is to develop an optimized platform offering innovative real-time media (video and data) applications for road monitoring in real scenarios. We exploit low-level efficient image features in order to enable our distributed system to extract semantic information from the imagery and to optimize the video compression adaptively.Other creatorsSee project
