Research overview:
This study is aiming at developing a new watermarking technique. Its distortion is less than that of the current ones, while retaining the extraction rate of watermarks. In order to attain this goal, auditory features, i.e., the insensitivity to phase and the binaural effects, are carefully investigated and exploited. (k2001.10)
