An audio watermarking scheme using singular value decomposition and dither-modulation quantization
Quantization index modulation is one of the best methods for performing blind watermarking, due to its simplicity and good rate-distortion-robustness tradeoffs. In this paper, a ne...

Multi-pitch estimation by a joint 2-d representation of pitch and pitch dynamics
Multi-pitch estimation of co-channel speech is especially challenging when the underlying pitch tracks are close in pitch value (e.g., when pitch tracks cross). Building on our pr...
