The Gabor expansion based positive distribution
نویسنده
چکیده
This paper presents and studies a time frequency distribution obtained from a Gabor expansion of a signal. The distribution is named the Positive Gabor Spectrogram, and is a new positive-like distribution with correct marginal distributions. Two side effects of correct marginals are non-additivity and time frequency fading. These are phenomena of a statistical correct distribution which do not agree with our intuitive expectation of a time frequency representation.

Evolutionary spectral analysis and the generalized Gabor expansion
In this paper, we present a connection between the discrete Gabor expansion and the evolutionary spectral theory. Including a scale parameter in the Gabor expansion, we obtain a new representation for deterministic signals that is analogous to the Wold-Cramer decomposition for non-stationary processes. The energy distribution resulting from the expansion is easily calculated from the Gabor coee...
متن کاملLearning 2D Gabor Filters by Infinite Kernel Learning Regression
Gabor functions have wide-spread applications in image processing and computer vision. In this paper, we prove that 2D Gabor functions are translation-invariant positive-definite kernels and propose a novel formulation for the problem of image representation with Gabor functions based on infinite kernel learning regression. Using this formulation, we obtain a support vector expansion of an imag...
متن کامل3D Gabor Based Hyperspectral Anomaly Detection
Hyperspectral anomaly detection is one of the main challenging topics in both military and civilian fields. The spectral information contained in a hyperspectral cube provides a high ability for anomaly detection. In addition, the costly spatial information of adjacent pixels such as texture can also improve the discrimination between anomalous targets and background. Most studies miss the wort...

In this paper, a new strategy based on a dynamic (time-based) model is proposed for expansion planning of electrical energy distribution systems, taking into account distributed generation resources and advantage of the techno-economic approach. In addition to optimal placement and capacity, the proposed model is able to determine the timing of installation / reinforcement of expansion options....
متن کاملTime and Frequency Split Zak Transform for Finite Gabor Expansion - Circuits and Systems, 1995. ISCAS '95., 1995 IEEE International Symposium on
The relationship between finite discrete Zak transform and finite Gabor expansion are well discussed in this paper. In this paper, we present two DFT-based algorithms for computing Gabor coefficients. One is based upon the time-split Zak transform, the other is frequencysplit Zak transform. These two methods are time and frequency dual pairs. Furthermore, we extend the relationship between fini...
