Mean shift for direction finding and separation of sound sources using microphone array

This paper proposes a mean shill based blind source separation method combining with source direction estimation using time-frequency (T-F) decomposition. Basic cue of each T-F cell is the wave propagation vector and the proposed method is applicable to arbitrary array configuration in 3-D space. Me...
