Pitch detection of an audio signal is an interesting research topic in the field of speech signal processing. Pitch is one of the most important perceptual features, as it conveys much information about the audio signal. It is closely related to the physical feature of fundamental frequency f0. For musical instrument sounds, the f0 and the measured pitch can be considered equivalent. In this paper...

To overcome the burden of sending authentication information separately, a noble reversible data embedding method is proposed. In this scheme, content based digital...
