This paper proposes a method able to exploit peculiarities of both, local and global shape descriptors, to be employed for shape classification and retrieval. In the proposed framework, the silhouettes of symbols are firstly described through Bags of Shape Contexts. The shape signature is then used to solve the correspondence problem between points of two(More)
In this paper an imaging system for road traffic conflict analysis is proposed. The system exploits geo-referenced stereo sequences and tracking procedure to compute traffic conflict measures which can be analysed by experts. Using the potentiality of the traffic conflict technique as a surrogate safety measure could constitute an effective tool in(More)

In this paper a vision based system for traffic conflict analysis is presented. The system employs geo-referenced stereo sequences and tracking procedure to provide much greater information regarding pre-crash and crash events than what is currently available. The exploitation of the traffic conflict technique potentiality as a surrogate safety measure(More)
In this paper an imaging system for bus traffic conflict investigation is presented. The system employs geo-referenced stereo sequences and tracking procedure to provide much greater information regarding pre-crash and crash events than what is currently available. The exploitation of the traffic conflict technique potentiality as a surrogate safety measure(More)
Multimedia Forensics is devoted to analyse digital multimedia contents such as photo, video and audio in order to produce evidences in the forensics domain. Specifically Image Forensics focuses on investigating on still images by analysing the authenticity and integrity of data (Forgery Detection) and by reconstructing the history of the image itself since(More)
A relevant research issue in naturalistic studies is related to analysis and evaluation of the huge data recorded during the experiment. A procedure to identify critical events of PTW is presented and tested using parameters measured or derived by GPS. Raw measures of speed, position and time are copied directly from the data string stored by the GPS in(More)
Image Forensics has already achieved great results for the source camera identification task on images. Standard approaches for data coming from Social Network Platforms cannot be applied due to different processes involved (e.g., scaling, compression, etc.). Over 1 billion images are shared each day on the Internet and obtaining information about their(More)
