Book Synopsis Audio-visual Person Tracking: A Practical Approach by : Fotios Talantzis
Download or read book Audio-visual Person Tracking: A Practical Approach written by Fotios Talantzis and published by World Scientific. This book was released on 2011-12-23 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the creation of the algorithmic backbone that enables a computer to perceive humans in a monitored space. This is performed using the same signals that humans process, i.e., audio and video. Computers reproduce the same type of perception using sensors and algorithms in order to detect and track multiple interacting humans, by way of multiple cues, like bodies, faces or speech. This application domain is challenging, because audio and visual signals are cluttered by both background and foreground objects. First, particle filtering is established as the framework for tracking. Then, audio, visual and also audio-visual tracking systems are separately explained. Each modality is analyzed, starting with sensor configuration, detection for tracker initialization and the trackers themselves. Techniques to fuse the modalities are then considered. Instead of offering a monolithic approach to the tracking problem, this book also focuses on implementation by providing MATLAB code for every presented component. This way, the reader can connect every concept with corresponding code. Finally, the applications of the various tracking systems in different domains are studied./a

Book Synopsis Computer After Me, The: Awareness And Self-awareness In Autonomic Systems by : Jeremy Pitt
Download or read book Computer After Me, The: Awareness And Self-awareness In Autonomic Systems written by Jeremy Pitt and published by World Scientific. This book was released on 2014-08-29 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are increasingly seeing computer systems which are expected to function without operator intervention. This is perhaps acceptable for running computer networks or traffic lights; however, we are now seeing computer systems deployed to qualitatively influence human judgments such as rulings on legal disputes or fitness for work to evaluate disability benefits. In keeping with the precautionary principle, it is important that those who are developing this capability — technologists and scientists — think through its potential implications.The aim of this book is to explore the technological and social and implications of computers and robots becoming increasingly ‘aware’ of their environment and the people in it, and their being increasingly ‘self-aware’ of their own existence within it.The wide-ranging scope of the text covers three different angles of the concept of ‘the computer after me’: (1) the next generation of computationally powerful aware systems; (2) systems in which the computer is aware of qualitatively impact human concerns such as law, health and rules; and (3) computers and robots which are aware of themselves.

Book Synopsis 3d Audio Visual Person Tracking Using Kalman Filtering and Information Theor by : Alexander Carter
Download or read book 3d Audio Visual Person Tracking Using Kalman Filtering and Information Theor written by Alexander Carter and published by Createspace Independent Publishing Platform. This book was released on 2017-02-03 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper proposes a system for tracking people in three dimensions, utilizing audiovisual information from multiple acoustic and video sensors. The proposed system comprises a video and an audio subsystem combined using a Kalman filter. The video subsystem combines in 3D a number of 2D trackers based on a variation of Stauffer's adaptive background algorithm with spacio-temporal adaptation of the learning parameters and a Kalman tracker in a feedback configuration. The audio subsystem uses an information theoretic metric upon a pair of microphones to estimate the direction from which sound is arriving from. Combining measurements from a series of pairs the actual coordinate of the speaker in space is derived.

Book Synopsis Audio-Visual Speaker Tracking by : Volkan Kılıç
Download or read book Audio-Visual Speaker Tracking written by Volkan Kılıç and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Target motion tracking found its application in interdisciplinary fields, including but not limited to surveillance and security, forensic science, intelligent transportation system, driving assistance, monitoring prohibited area, medical science, robotics, action and expression recognition, individual speaker discrimination in multi-speaker environments and video conferencing in the fields of computer vision and signal processing. Among these applications, speaker tracking in enclosed spaces has been gaining relevance due to the widespread advances of devices and technologies and the necessity for seamless solutions in real-time tracking and localization of speakers. However, speaker tracking is a challenging task in real-life scenarios as several distinctive issues influence the tracking process, such as occlusions and an unknown number of speakers. One approach to overcome these issues is to use multi-modal information, as it conveys complementary information about the state of the speakers compared to single-modal tracking. To use multi-modal information, several approaches have been proposed which can be classified into two categories, namely deterministic and stochastic. This chapter aims at providing multimedia researchers with a state-of-the-art overview of tracking methods, which are used for combining multiple modalities to accomplish various multimedia analysis tasks, classifying them into different categories and listing new and future trends in this field.

Book Synopsis Audio Visual Information Fusion for Human Activity Analysis by : Shankar Thagadur Shivappa
Download or read book Audio Visual Information Fusion for Human Activity Analysis written by Shankar Thagadur Shivappa and published by . This book was released on 2010 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human activity analysis in unconstrained environments using far-field sensors is a challenging task. The fusion of audio and visual cues enables us to build robust and efficient human activity analysis systems. Traditional fusion schemes including feature-level, classifier-level and decision-level fusion have been explored in task-specific contexts to provide robustness to sensor and environmental noise. However, human activity analysis involves the extraction of information from audio and visual cues at multiple levels of semantic abstraction. This naturally leads to a hierarchical fusion framework. In this dissertation, the limitations of existing fusion schemes are explored and new algorithms are developed to address some of these limitations. The iterative decoding algorithm (IDA) fuses the audio and video modalities at the decision level but unlike other schemes, it uses an iterative strategy to infer the joint likelihood of the hidden states from the unimodal likelihoods. The iterative decoding is advantageous to joint modeling and other decision level fusion schemes in terms of ease of training of the models and the performance under low SNR scenarios. The extension of the IDA to more complex tasks, such as audio-visual person tracking and meeting scene analysis, leads to hierarchical fusion frameworks. The multilevel iterative decoding framework for audio-visual person tracking (MID-AVT) uses the iterative decoding framework for tracking multiple subjects using both audio and visual cues from multiple cameras and microphone arrays. The local sensor-level tracks are fused using the IDA to obtain globally consistent tracks. The MID-AVT framework is robust to sensor calibration errors and requires only a rough calibration step to learn the correspondences between different sensors. The location specific speaker modeling (LSSM) framework for audio-visual meeting scene analysis augments the tracking information with speaker recognition information. Speaker recognition using far-field microphones is a challenging task. The LSSM framework addresses this issue by using the speaker's location information to select the corresponding location specific speaker recognition model. In practice, training such contextual models requires intensive labeling of audio-visual datasets. Semi-supervised techniques for model learning and sensor calibration are presented in this dissertation to address this issue. A particular case, learning the LSSM models using face recognition information, is explored in detail and found to perform well in practice. The overall contribution of this dissertation is the exploration of various aspects of hierarchical fusion in audio-visual human activity analysis and the extensive analysis of these hierarchical fusion frameworks on real world audio-visual testbeds.
