Singing voice analysis has been a topic of research to assist several applications in the domain of music information retrieval system. One such major area is singer identification (SID). There has been enormous increase in production of movies and songs in Bollywood industry over the last 50 decades. Surveying this extensive dataset of singers, the paper presents singer identification system for...
The paper presents a novel approach to identify the singers using harmonic spectral envelope constructed from pitch of singing voice. This new representation of singing voice demonstrates that harmonic spectral envelope exhibits certain acoustic qualities that can characterize the identity of the singer. Two different approaches are implemented to extract the pitch of singing voice; Cepstrum technique...
Formants are the frequency parts of speech and singing signal those closely describe the human vocal tract geometry. Considering the growing importance of the formants, they are considered the important subject of many work. In this sense, we present two techniques for the estimation of formants, one combining Wavelet with Linear Predictive Coding (LPC) and the other combining Wavelet with Cepstral...
Texture is an inherent property of a fabric whose periodicity can be extracted from DC Suppressed Fourier Power Spectrum Sum (DCSFPSS). Periodicity can be used as one of the fabric quality parameters to detect the woven fabric defects. This paper focuses on modeling periodicity of a plain weave fabric based on DCSFPSS and using this model to detect the fabric defects. The nonparametric and parametric...
In recent years an engineer or technocrat graduated from any country is expected to provide his/her services to any location of the globe for the betterment of mankind. In this respect it has become necessary that an engineering graduate possesses a set of skills which encompass technical knowledge, practical skills and right attitude. Every educational program defines its program educational objectives...
With increased complexity in control and automation systems, efforts are going on for developing reliable and safe control systems. IEC61131-3 is most commonly used control specification standard. Development of IEC61499 is an effort to utilize proven software engineering practices that can provide benefits such as portability, interoperability, configurability and re-configurability to these systems...
Iris recognition, a relatively new biometric technology, has great advantages, such as variability, stability and security, thus it is the most promising for high security environments. Hence numbers of IRIS recognition algorithms are proposed, such as ICA (independent component analysis), SVD (singular value decomposition), Characterizing key local variation etc. which extracts iris features and...
The Quadrature Mirror Filter (QMF) basically is a parallel combination of of a High Pass Filter (HPF) and Low Pass Filter (LPF), which performs the action of frequency subdivision by splitting the signal spectrum into two spectra. Thus QMF finds wide applications in many signal processing tasks such as transmultiplexing, equalizing wireless communication channels; sub-band coding of speech and image...
The aspect of intellectual property protection (IPP) has created a deep concern in recent years which has forced the IP owners to incorporate some sort of signature or watermark in their designs. In this regard, Oliveira have suggested a technique of modifying the state transition graph (STG) of sequential circuits incorporating digital watermark in such a way that it is impossible for anyone to even...
