Abstract

This paper presents a method for a robotic ear based on the spatio-temporal gradient analysis with blind signal separation that estimates the object signals from overlapped signals. By using the spatial derivatives of mixed signals, not only the object source signals but also the arrival directions are estimated. The effectiveness of the proposed method is confirmed through the numerical experiment.
