Audio Source Localization using a Network of Embedded Devices

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Audio Data Fuzzy Fusion for Source Localization

Information-Driven Active Audio-Visual Source Localization

We present a system for sensorimotor audio-visual source localization on a mobile robot. We utilize a particle filter for the combination of audio-visual information and for the temporal integration of consecutive measurements. Although the system only measures the current direction of the source, the position of the source can be estimated because the robot is able to move and can therefore ob...

A Comparative Error Analysis of Audio-Visual Source Localization

This paper examines the accuracy of audio-video based localization using multiple cameras and multi-microphones. Covariance mapping theory is used to determine the accuracy of audio and video based localization. Both modalities are compared in terms of their ability to provide accurate location estimates of a moving audio-visual source. Relatively, video is found to be significantly more accura...

On Building Immersive Audio Applications Using Robust Adaptive Beamforming and Joint Audio-Video Source Localization

This paper deals with some of the different problems, strategies, and solutions of building true immersive audio systems oriented to future communication applications. The aim is to build a systemwhere the acoustic field of a chamber is recorded using amicrophone array and then is reconstructed or rendered again, in a different chamber using loudspeaker array-based techniques. Our proposal expl...
