Natural and Collaborative Interaction System for for Medical Environments

Project and Development of a Natural and Collaborative Interaction System for Medical Environments. The System should provide and support access to information, the visualization and manipulation of the results in the most natural way possible. For this reason it is required the integration of a set of modules hardware/software that support the manipulation of multimedia informations through collaborative tools based on paradigms of natural interaction.

Here we present a set of actions:

Compact hash codes and data structures for efficient mobile visual search

We present an efficient method for mobile visual search that exploits compact hash codes and data structures for visual features retrieval. The method has been tested on a large scale standard dataset of one million SIFT features, showing a retrieval performance comparable or superior to state-of-the-art methods, and a very high efficiency in terms of memory consumption and computational requirements. These characteristics make it suitable for application to mobile visual search, where devices have limited computational and memory capabilities.

Reddit Crawler in Python

Code of a Reddit Crawler written in Python


Reddit /ˈrɛdɪt/,[4] stylized as reddit,[5] is an entertainment, social networking service and news website where registered community members can submit content, such as text posts or direct links. Only registered users can then vote submissions “up” or “down” to organize the posts and determine their position on the site’s pages. Content entries are organized by areas of interest called “subreddits”.

Reddit was founded by University of Virginia roommates Steve Huffman and Alexis OhanianCondé Nast Publications acquired the site in October 2006. Reddit became a direct subsidiary of Condé Nast’s parent company, Advance Publications, in September 2011. As of August 2012, Reddit operates as an independent entity, although Advance is still its largest shareholder.[6] Reddit is based in San Francisco, California. In October 2014 Reddit received $50 million in funding from Snoop Lion and other investors.[7]

C++ Ransac Method Implementation

Ransac Method implemented in C++ for robust keypoints estimation in Computer Vision


Random sample consensus (RANSAC) is an iterative method to estimate parameters of a mathematical model from a set of observed data which contains outliers. It is a non-deterministic algorithm in the sense that it produces a reasonable result only with a certain probability, with this probability increasing as more iterations are allowed. The algorithm was first published by Fischler and Bolles at SRI International in 1981.

A basic assumption is that the data consists of “inliers”, i.e., data whose distribution can be explained by some set of model parameters, though may be subject to noise, and “outliers” which are data that do not fit the model. The outliers can come, e.g., from extreme values of the noise or from erroneous measurements or incorrect hypotheses about the interpretation of data. RANSAC also assumes that, given a (usually small) set of inliers, there exists a procedure which can estimate the parameters of a model that optimally explains or fits this data.

Opening the visitor center with “MyFirenze” project (Firenze Santa Maria Novella)

On 4 April 2014 was opened a new visitor center in Piazza Stazione near Santa Maria Novella’s train station (Firenze). This opening has involved a project developed by the Micc (Media Integration and Communication Center -University of Florence) lab in collaboration with the municipality of Florence.

The project name is “MyFirenze” and it is a framework for itinerary personalization which includes the use of a touchscreen correlated with the use of a mobile device.


here some newspaper articles from two italian newspapers :

AI*HCI 2013 (Workshop)




AI*HCI 2013 is a Workshop of the XIII AI*IA Conference which took place in Torino on 4 of December 2013. The main aim of this workshop is to bridge Artificial Intelligence and Human Computer Interaction. 

I presented a recent work about Itinerary Personalization in the context of Smart Cities

Feature Matching and Planar Homography with Overlay – Android + OpenCv

This a video about a test (for my master thesis) with and Android device and OpenCv libraries. The purpose of this test was to run on a device a Feature Matching and Planar Homography with a final overlay. This was possible using the power offered by OpenCv.

Elementi di Software Dependability

 La pervasivita’ del software in una miriade di oggetti di cui ci serviamo ogni giorno per le piu’ svariate attivita’ e’ nota. Questa pervasivita’ rende impellente la necessita’ che il software sia esente da guasti.
Il corso si propone di illustrare una serie di tecniche che consentono di ovviare per quanto possibile al problema dell’introduzione di errori di progetto nella produzione del software; quindi, principalmente, tecniche di verifica formale e di sviluppo formale del software, ma anche tecniche di previsone dei guasti e di tolleranza ai guasti. Saranno studiati i costi dell’introduzione di queste tecniche in un contesto produttivo, e come il processo produttivo si debba relazionare a normative specifiche di alcuni settori di produzione industriale del software.
