Measurement of Distance and Velocity of Moving Objects using Single Camera Pseudo-Stereo Images
Jae-Soo Lee,Soo-In Kim,In-Ho Choi 한국조명·전기설비학회 2007 조명·전기설비학회논문지 Vol.21 No.9
In this study, a new algorithm for measuring the velocity and distance from a camera to a moving object by using pseudo-stereo images obtained from a single camera with a stereo adapter is proposed. The proposed system is similar to a parallel visual stereo system using a two-camera system, but because this system can obtain pseudo-stereo images form a single camera, it has advantages not only in the aspect of cost but also in stereo conformity by arrangement and the calibration of the left and right stereo cameras upon image processing.

Multi-Channel Hybrid Acoustic Echo Canceller with Microphone/Speaker Array
Shigenobu Minami,Hirokazu Tanaka,Miki Haseyama 대한전자공학회 2009 ITC-CSCC :International Technical Conference on Ci Vol.2009 No.7
An audio system which integrates an acoustic echo canceller (AEC) and Microphone/Speaker (MIC/SP) array is proposed. To cope with both miss-convergence of AEC due to strong cross-channel correlation (CCC) in stereo sound and echo path change by beam-forming function in MIC/SP array, Multi-Channel Hybrid AEC (MCH-AEC) which is based on PST-EC[10] method is extended to be applicable to MIC/SP array system. Since the MCH-AEC dominates system performance, CCC and acoustic echo cancellation performances (ERLE) of the method are evaluated by using computer simulations.
