Beschreibung

The presentation will report on our work on estimating localization accuracy when using audio time-delay estimates in reverberant rooms. In this work we employed an extension of the Cramér-Rao lower limit on the variance of the estimate that takes account of anomalies arising due to reflections.

Astrategy for optimum placement of microphone arrays for speaker localization will be discussed. Astudy we have conducted of the performance of fusion strategies for combined audio-video localization will be summarized.

The presentation will also introduce our current work on approximation and interpolation of binaural head and room impulse responses with some discussion of how this might be used in source localization.
