Lathoud, GuillaumeOdobez, Jean-MarcGatica-Perez, Daniel2006-03-102006-03-102006-03-10200510.1007/978-3-540-30568-2_16https://infoscience.epfl.ch/handle/20.500.14299/228634Assessing the quality of a speaker localization or tracking algorithm on a few short examples is difficult, especially when the ground-truth is absent or not well defined. One step towards systematic performance evaluation of such algorithms is to provide time-continuous speaker location annotation over a series of real recordings, covering various test cases. Areas of interest include audio, video and audio-visual speaker localization and tracking. The desired location annotation can be either 2-dimensional (image plane) or 3-dimensional (physical space). This paper motivates and describes a corpus of audio-visual data called ``AV16.3'', along with a method for 3-D location annotation based on calibrated cameras. ``16.3'' stands for 16 microphones and 3 cameras, recorded in a fully synchronized manner, in a meeting room. Part of this corpus has already been successfully used to report research results.speechvisionlathoudodobezgaticatext::conference output::conference proceedings::conference paper
