3048 Recognizing an Individual, Their Topic of Conversation and Cultural Background from 3D Body Movement
Authors: Gheida J. Shahrour, Martin J. Russell
Abstract:
The 3D body movement signals captured during human-human conversation include clues not only to the content of people’s communication but also to their culture and personality. This paper is concerned with automatic extraction of this information from body movement signals. For the purpose of this research, we collected a novel corpus from 27 subjects, arranged them into groups according to their culture. We arranged each group into pairs and each pair communicated with each other about different topics. A state-of-art recognition system is applied to the problems of person, culture, and topic recognition. We borrowed modeling, classification, and normalization techniques from speech recognition. We used Gaussian Mixture Modeling (GMM) as the main technique for building our three systems, obtaining 77.78%, 55.47%, and 39.06% from the person, culture, and topic recognition systems respectively. In addition, we combined the above GMM systems with Support Vector Machines (SVM) to obtain 85.42%, 62.50%, and 40.63% accuracy for person, culture, and topic recognition respectively. Although direct comparison among these three recognition systems is difficult, it seems that our person recognition system performs best for both GMM and GMM-SVM, suggesting that inter-subject differences (i.e. subject’s personality traits) are a major source of variation. When removing these traits from culture and topic recognition systems using the Nuisance Attribute Projection (NAP) and the Intersession Variability Compensation (ISVC) techniques, we obtained 73.44% and 46.09% accuracy from culture and topic recognition systems respectively.Keywords: person recognition, topic recognition, culture recognition, 3D body movement signals, variability compensation

Authors: Hassam Muazzam
Abstract:
This paper devises an autonomous self-driven vehicle that is capable of taking a disabled person to his/her desired location using three different power sources (gasoline, solar, electric) without any control from the user, avoiding the obstacles in the way. The GPS co-ordinates of the desired location are sent to the main processing board via a GSM module. After the GPS co-ordinates are sent, the path to be followed by the vehicle is devised by Pythagoras theorem. The distance and angle between the present location and the desired location is calculated and then the vehicle starts moving in the desired direction. Meanwhile real-time data from ultrasonic sensors is fed to the board for obstacle avoidance mechanism. Ultrasonic sensors are used to quantify the distance of the vehicle from the object. The distance and position of the object is then used to make decisions regarding the direction of vehicle in order to avoid the obstacles using artificial neural network which is implemented using ATmega1280. Also the vehicle provides the feedback location at remote location.Keywords: autonomous self-driven vehicle, obstacle avoidance, desired location, pythagoras theorem, neural network, remote location

Authors: Ren Moses, Jaqueline Masaki
Abstract:
This paper addresses the need for accurate and updated vehicle classification system through a thorough evaluation of vehicle class categories to identify errors arising from the existing system and proposing modifications. The data collected from two permanent traffic monitoring sites in Florida were used to evaluate the performance of the existing vehicle classification table. The vehicle data were collected and classified by the automatic vehicle classifier (AVC), and a video camera was used to obtain ground truth data. The Federal Highway Administration (FHWA) vehicle classification definitions were used to define vehicle classes from the video and compare them to the data generated by AVC in order to identify the sources of misclassification. Six types of errors were identified. Modifications were made in the classification table to improve the classification accuracy. The results of this study include the development of updated vehicle classification table with a reduction in total error by 5.1%, a step by step procedure to use for evaluation of vehicle classification studies and recommendations to improve FHWA 13-category rule set. The recommendations for the FHWA 13-category rule set indicate the need for the vehicle classification definitions in this scheme to be updated to reflect the distribution of current traffic. The presented results will be of interest to States’ transportation departments and consultants, researchers, engineers, designers, and planners who require accurate vehicle classification information for planning, designing and maintenance of transportation infrastructures.Keywords: vehicle classification, traffic monitoring, pavement design, highway traffic

Authors: Robert Monsberger
Abstract:
The increasing scarcity of resources and the pressing challenge of climate change demand transformative technological, economic, and societal approaches. In alignment with the European Green Deal's goal to achieve net-zero greenhouse gas emissions by 2050, this paper presents the development and implementation of an electronic parking and mobility system (ePAM). This system offers a distinct, integrated solution aimed at promoting climate-positive mobility, reducing individual vehicle use, and advancing the digital transformation of off-street parking. The core objectives include the accurate recognition of electric vehicles and occupant counts using advanced camera-based systems, achieving a very high accuracy. This capability enables the dynamic categorization and classification of vehicles to provide fair and automated tariff adjustments. The study also seeks to replace physical barriers with virtual ‘digital gates’ using augmented reality, significantly improving user acceptance as shown in studies conducted. The system is designed to operate as an end-to-end software solution, enabling a fully digital and paperless parking management system by leveraging license plate recognition (LPR) and metadata processing. By eliminating physical infrastructure like gates and terminals, the system significantly reduces resource consumption, maintenance complexity, and operational costs while enhancing energy efficiency. The platform also integrates CO₂ reporting tools to support compliance with upcoming EU emission trading schemes and to incentivize eco-friendly transportation behaviors. By fostering the adoption of electric vehicles and ride-sharing models, the system contributes to the optimization of traffic flows and the minimization of search traffic in urban centers. The platform's open data interfaces enable seamless integration into multimodal transport systems, facilitating a transition from individual to public transportation modes. This study emphasizes sustainability, data privacy, and compliance with the AI Act, aiming to achieve a market share of at least 4.5% in the DACH region by 2030. ePAM sets a benchmark for innovative mobility solutions, driving significant progress toward climate-neutral urban mobility.Keywords: sustainable mobility, digital parking, AI-driven vehicle recognition, license plate recognition, virtual gates, multimodal transport integration

Abstract:
In this paper, we propose an improved face recognition algorithm using histogram-based features in spatial and frequency domains. For adding spatial information of the face to improve recognition performance, a region-division (RD) method is utilized. The facial area is firstly divided into several regions, then feature vectors of each facial part are generated by Binary Vector Quantization (BVQ) histogram using DCT coefficients in low frequency domains, as well as Local Binary Pattern (LBP) histogram in spatial domain. Recognition results with different regions are first obtained separately and then fused by weighted averaging. Publicly available ORL database is used for the evaluation of our proposed algorithm, which is consisted of 40 subjects with 10 images per subject containing variations in lighting, posing, and expressions. It is demonstrated that face recognition using RD method can achieve much higher recognition rate.Keywords: binary vector quantization (BVQ), DCT coefficients, face recognition, local binary patterns (LBP)
