Generating fractal rough surfaces with the spectral representation method [PDF]

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2021
The application of the spectral representation method in generating Gaussian and non-Gaussian fractal rough surfaces is studied in this work. The characteristics of fractal rough surfaces simulated by the spectral representation method and the ...

Spectral Invariant Representation for Spectral Reflectance Image

2010 20th International Conference on Pattern Recognition, 2010
Although spectral images contain large amount of information, compared with color images, the image acquisition is affected by several factors such as shading and specular highlight. Many researchers have introduced color invariant and spectral invariant representations for these factors using the standard dichromatic reflection model of inhomogeneous ...

Mixing spectral representations of graphs

18th International Conference on Pattern Recognition (ICPR'06), 2006
Generative models are well known in the domain of statistical pattern recognition. Typically, they describe the probability distribution of patterns in a vector space. The individual patterns are defined by vectors and so the individual features of the pattern are well defined.

Spectral representation of transient signals

2014 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2014
Signal processing techniques exploiting natural and efficient representations of a class of signals with an underlying parametric model have been extensively studied and successfully applied across many disciplines. In this paper, we focus attention to the representation of one such class, i.e. transient structured signals.

Spectral Representations of Nonmodal Phonation

IEEE Transactions on Audio, Speech, and Language Processing, 2008
Regions of nonmodal phonation, which exhibit deviations from uniform glottal-pulse periods and amplitudes, occur often in speech and convey information about linguistic content, speaker identity, and vocal health. Some aspects of these deviations are random, including small perturbations, known as jitter and shimmer, as well as more significant ...

A spectral invariant representation of spectral reflectance

Optical Review, 2011
Spectral image acquisition as well as color image is affected by several illumination factors such as shading, gloss, and specular highlight. Spectral invariant representations for these factors were proposed for the standard dichromatic reflection model of inhomogeneous dielectric materials.
