• 論文抄録(英) / 内容記述: We present a system for video retrieval based on analyzing audio data from a large number of microphones in a ubiquitous home. Silence elimination on individual microphones is followed by noise reduction based on regions consisting of multiple microphones, to identify audio segments. An algorithm based on the energy distribution of sounds in the house is used to localize sound sources, thereby removing sounds heard in regions other than they were generated. The algorithms were evaluated with 200 minutes of audio data from each of the microphones, gathered during an experiment during which a family lived in the ubiquitous home. It was possible to achieve an overall accuracy of above 80% from all algorithms.
