| Abstract | Audio has a key index in digital videos that can provide useful information for video editing, such as capturing con-versations only, clipping only talking people, and so on. In this paper, we are studying about video editing based on audio with a two-channel (stereo) microphone that is stan-dard equipment on video cameras, where the video con-tent is automatically recorded without a cameraman. In order to capture only a talking person on video, a novel voice/non-voice detection algorithm using AdaBoost, which can achieve extremely high detection rates in noisy environ-ments, is used. In addition, the sound source direction is es-timated by the CSP (Crosspower-Spectrum Phase) method in order to zoom in on the talking person by clipping frames from videos, where a two-channel (stereo) microphone is used to obtain information about time differences between the microphones. 1. |
