Short bio

Carla Maria Modena received her degree in Mathematics from the University of Trento in 1985. In 1986, she worked as research assistant (Wissenschaftliche Mitarbeiterin) in Ökonometrie at the Institut für Volkswirtschaftslehre, Universität Regensburg, Germany.
She joined ITC-irst, now FBK (Trento - Italy) in 1987, where she works with the Technologies of Vision (TeV) research unit.

She is interested in text detection and extraction for document image understanding (DIU and OCR) and for scene understanding (TIS). She works mainly on computer vision with applicative tasks (for example, traffic scene analyis, people re-identification). To prevent the risk of reinventing the wheel, she pays a close attention to the state-of-the art before starting each task in which she is involved in, using her ability to fully exploit the net resources and to analyse trends in upcoming conferences.

She is a member of IAPR-CVPL.

    Segmentation of sport videos by embedded text reading,
    This report presents a module for athlete recognition in broadcast videos as part of a video entertainment application. The aim is to identify athletes by means of name or number as printed on their uniform and extract the video clips where the desired athlete is visible. Using an adaptation of a previously published algorithm we extract text from each single frame and we read it by means of an optical character recognizer (OCR). The OCRed text is then compared with an a-priori known list of athletes' names or numbers to provide a score of the presence of each athlete in that frame. Presence plausibility is then checked by a temporal persistence analysis of names/numbers extracted from subsequent frames.

    Performed experiments show that the method is promising and can provide a useful input for a module for the identification of the athlete presence in a frame.

    Recognition and tracking of embedded text in sport videos: a case study,
    Abstract - We present an athlete recognition module designed for broadcast videos, forming part of a system designed for the personalization of sport video broadcast. The aim of this module is the identification of athletes in the scene through the reading of names or numbers printed on their uniforms and to identify frames where athletes are visible. Using an adaptation of a previously published algorithm we extract text from individual frames and then read these candidates by means of an optical character recognizer (OCR). The OCR-ed text is then compared to an a-priori list of athletes' names (or numbers), to provide a presence score for each athlete. Text regions are subsequently tracked in following frames using a template matching technique. In this way blurred or distorted text, normally unreadable by the OCR, can also be exploited to provide a denser labelling of the video sequences.,

    Extended Traffic Data Collection by Intelligent Vehicles,
    The elaboration of floating car data, i.e. data collected by vehicles moving on road network, is relevant for traffic management and for private service providers, which can bundle updated traffic information with navigation services. Floating data, in its extended acceptation, contains not only time and location provided by an on-board positioning system, but also information coming from othervarious vehicle sensors.In this report we describe our extended data collection system, in which vehicles are able to collect data about their local environment, namely the presence of roadworks and traffic slowdowns, by analyzing visual data taken by a looking forward camera and data from the on-board Electronic Control Unit. Upon detection of such events, apacket is set up containing time, position, vehicle data, results of on-board elaboration, one or more images of the road ahead and an estimation of the local traffic level. Otherwise, the transmitted packet containing only the minimal data, making its size adaptive to the environment surrounding the vehicle.,

    A Computer Vision System for Traffic Accident Risk Measurement: A Case Study,
    Abstract - A reliable estimation of the safety level of the roads is a valuable tool for detecting critical points in the road infrastructure, planning and implement countermeasures, and evaluating their impact on the traffic. A method for the computation of the accident risk is proposed, which is based on microscopic traffic data collected automatically by a video-based monitoring system, i.e. class, speed, and tra jectory of each single road-user. The benefit of the proposed method is twofold: the risk level is computed without statistics on past accidents, and its computation is fully automated, i.e. it does not require a manual collection of traffic data. The paper presents the definition of the proposed risk index and
    describes its application to a real case: the evaluation of the accident risk at an urban intersection, before and after the reorganization of its geometry. The proposed risk index, although based only on those parameters that are automatically measurable, seems to reflect the expectation of traffic experts in evaluating the impact of intervention to improve the safety level of the intersection.
