朴貴泰,金甲一 明知大學校 産業技術硏究所 2005 産業技術硏究所論文集 Vol.24 No.-
In this paper, we present a wireless watermarking technique for a new character robot. After we insert a sequence of some action codes inaudibly to an audio signal, the character can act the behaviors indicated in those codes by processing sound with a microphone and extracting concealed codes when the pre-processed audio file is played. For example, the robot dances to the music where the action codes were concealed. For this, we propose a modified echo-hiding algorithm. This modified algorithm uses repeated watermarks for robust extraction and integer watermarks for enough data insertion so that it can solve technical problems with the noise generated in the wireless analog channel, attenuation of sound in proportion to distance between a robot and a source of sound, and synchronization. Finally, we verify the performance of the proposed technique through experiments under several conditions.
