, 1965 The spectral representation of a countable family of mutually permutable self-adjoint operators is established. It is compared with the representation obtained from the Gelfand isomorphism of an Abelian Banach algebra. The spectral representations as described here can serve as an adequate substitute for the so called «expansion postulate» of quantum ...

Enhanced representation of spectral contrasts in the primary auditory cortex
Frontiers in Systems Neuroscience, 2013 The role of early auditory processing may be to extract some elementary features from an acoustic mixture in order to organize the auditory scene. To accomplish this task, the central auditory system may rely on the fact that sensory objects are often ...

Spectral representation of fingerprints [PDF]
, 2007 Most fingerprint recognition systems are based on the use of a minutiae set, which is an unordered collection of minutiae locations and directions suffering from various deformations such as translation, rotation and scaling. The spectral minutiae representation introduced in this paper is a novel method to represent a minutiae set as a fixed-length ...

Spectral minutiae representations for fingerprint recognition [PDF]
2010 Sixth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2010 Nowadays, biometric technology is increasingly deployed in civil and commercial applications. The growing use of biometrics is raising security and privacy concerns about the biometric technology. Storing biometric data, known as biometric templates, in a database leads to several privacy risks such as identity fraud and cross matching.

Nonsquare Spectral Factorization for Nonlinear Control Systems [PDF]
, 2005 This paper considers nonsquare spectral factorization of nonlinear input affine state space systems in continuous time. More specifically, we obtain a parametrization of nonsquare spectral factors in terms of invariant Lagrangian submanifolds and ...

Hyperspectral Image Denoising via Nonlocal Spectral Sparse Subspace Representation
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 Hyperspectral image (HSI) denoising based on nonlocal subspace representation has attracted a lot of attention recently. However, most of the existing works mainly focus on refining the representation coefficient images (RCIs) using certain nonlocal ...
