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.

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.

A framework for itinerary personalization in cultural tourism of smart cities

Smart tourism in cities of art is a personalized user experience that exploits smart city infrastructures to offer increased opportunities of visit and services and time optimization. Traditionally, this capability requires the availability of personal mobile systems and geolocalization, augmented with some smart computing that provides the due information and functions at the right time and location of the visit. However effective smart tourism should also account for the fact that they exist different user requirements at different stages of the visit and that interests and requirements not only differ from one user to the other but also may change through time for each individual user. According to this, an effective framework for smart tourism should offer the possibility of an easy definition of individual user visits and offer to each user the capability of making changes or updates to his/her visit plan during the visit. It should also consider the possibility that different devices are offered and used at the different stages of the visit. In this work we present the prototype of a framework where different devices are used for the definition and modification of a personalized visit. In particular it exploits a wall mounted touchscreen in a visitor center which permits the early definition of a visit plan and a mobile device which allows online updates and changes of the planes well as display of geolocalized information during the time of the visit. An application server platform and a network infrastructure allows to record user activities as well as search and retrieve personalized data.
