Design and implementation of vibrotactile sensor of depth The main idea was to create a tool able to stimulate the user to sense spatial depth from a tactile input. In particular we have created a table with four pressure sensors able to give four different sounds and haptic feedbacks [PDF]
Analysis of eye motions using AAM The general purpose of this project, in collaboration with Dr. Manganotti, was to analyze video sequences involving epileptic patients. In particular, we created a classifier able to discriminate different stages of an epileptic seizure. To face this problem we used some techniques based on Active Appearance Models (AAM). [PDF]
Extend mElite game Extend the mElite game located in the space. You can negotiate objects, fuel, planets. For each asteroid you destroy, you earn money and life.
Gesture interaction with markers The aim was to use ARToolkit for designing 3D models. The program is able to recognize drawn and printed patterns (like a shape). We studied a mechanism to make the user interact with the program not only through a simple marker, but through keyboard or fingers motion. [Slides] [Video]
This dataset is used for studying personal aesthetics, a recent soft biometrics application where the goal is to recognize people from the images they like. It's composed of 200 users, 40K images. Given a set of preferred image of a user. [Dataset] PUBLICATIONS: [ACCV14] [ICMI14] [IEEEForensics14] [ICIP14]
This dataset is used to infer both self-assessed and attributed personality traits (Big-Five Traits) of Flickr users from their galleries of favorite pictures. The datset is composed of 60,000 pictures tagged as favorite by 300 users. [Dataset] [Code Features] PUBLICATIONS: [CVIU16] [IEEEAC16] [ACMBNI13]
I attended a bachelor degree in Multimedia Information Technology at the University of Verona, where I was mainly interested in Computer Vision, Augmented Reality, Human Computer Interaction, Computer Graphics and also Perception. My bachelor degree thesis proposed a face recognition system, that has been installed at the door of the VIPS laboratory of the University of Verona. I completed a master degree on Engineering and Computer Science with a thesis focused on the research field of Social Signal Processing (SSP), the domain aimed at modeling, analysis and synthesis of nonverbal communication in human-human and human-machine interactions. The purpose of the thesis was the person re-identfication through the way people chat with other subjects. During that period, I was lucky enough to work also on other research projects, like recognizing the age of children by the way they talk with each other. SSP together with, Social Media Analysis, Personality Computing, Machine Learning and Computer Vision became the main topics of my PhD at the Dept. of Computer Science in Verona (Italy). During the first year of PhD I investigated the interplay between aesthetic preferences and individual differences, under the supervision of Marco Cristani. I had the great opportunity to move to Glasgow for some months and collaborate with Alessandro Vinciarelli to this project. I collected a dataset of 60K images favorited from Flickr users, extracted features coming from the field of Computational Aesthetics (CA), and predicted from them the personality of a user. Continuing on the perspective of CA, we also proposed a soft biometrics application where the goal is to recognize people by considering the images they like as a new biometric trait. At the end of the second year of PhD I moved for some months in Birmingham to collaborate with Mirco Musolesi with the aim of investigating the role of textual, visual and social cues in information propagation in Twitter. My last contribute during the PhD was in the field of Deep Learning and Representation Learning, trying generalize the particular cues that characterize each personality trait. While waiting to defend my Phd thesis, I worked as research associate at Disney Research in Pittsburgh (PA). After my graduation, I moved to Pasadena (CA) to work as postdoctoral scholar at California Institute of Technology (Caltech), in the Computational Vision Lab, under the supervision of Pietro Perona and to collaborate with David Anderson. Here I worked on animal behavior, in particular, Computational Ethology, which involves biologists and computer scientists with the common goal of understanding, analyzing, measuring and describing animal behavior using Machine Learning and Machine Vision algorithms and tools. My role here was to develop a novel system able to detect, track and recognize mice actions on videos. Currently I am a research scientist at Disney Research LA, working on Machine Learning, Computer Vision, Emotional AI and Affective Computing and Perception with the goal of creating new magic experiences in the theme parks, resorts, hotels and cruiseships.
