Many watermark algorithms exist for the the frequency domain using the DCT or the DWT. In this paper, we propose a new watermark algorithm using the DWT for harmony with the human visual system, and the DCT for robustness against signal processing attacks.
This paper presents a system that enables the drum beats to be automatically detected using auditory cues and will be used ina drum-based human-robot interaction game. In pursuit of creating an interactive drumming game, where a human user is able to play drums with a humanoid robot relying on turn-taking and imitation principles, in this work, we… (More)
Super-orthogonal space-time trellis codes (SOSTTC) given in  are full rate, full diversity space-time codes with high coding gains for quasi-static fading channels. In this paper, this design approach is extended to fast fading channels and new SOSTTCs are proposed for BPSK and QPSK modulations based on the design criteria valid for this type of… (More)
