Minimizing and maximizing the joint space-spatial frequency uncertainty of Gabor-like functions: comment.
نویسندگان
چکیده
We dispute the claim that Hermite functions (similar to derivatives of Gaussians) minimize a joint uncertainty relation in space and spatial frequency. These functions are found to maximize rather than minimize the uncertainty of the class of functions consisting of an mth-order polynomial times a Gaussian.

3D 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...
متن کاملMaximum Maintainability of Complex Systems via Modulation Based on DSM and Module Layout.Case Study:Laser Range Finder
The present paper aims to investigate the effects of modularity and the layout of subsystems and parts of a complex system on its maintainability. For this purpose, four objective functions have been considered simultaneously: I) maximizing the level of accordance between system design and optimum modularity design,II) maximizing the level of accessibility and the maintenance space required,III...
متن کاملClassification of Endometrial Images for Aiding the Diagnosis of Hyperplasia Using Logarithmic Gabor Wavelet
Introduction: The process of discriminating among benign and malignant hyperplasia begun with subjective methods using light microscopy and is now being continued with computerized morphometrical analysis requiring some features. One of the main features called Volume Percentage of Stroma (VPS) is obtained by calculating the percentage of stroma texture. Currently, this feature is calculated ...
متن کاملMemory Module Processing
Both from a mathematical as well as a biological perspective, Wavelet transforms present themselves as an attractive means for extracting low-level information from an image. We present a processor-time optimal algorithm to implement wavelet transforms on a VLSI implementable parallel digital architecture. A desirable initial processing step in an artiicial vision system is the identiication of...
متن کاملThe two-dimensional Gabor function adapted to natural image statistics: An analytical model of simple-cell responses in the early visual system
The two-dimensional Gabor function is adapted to natural image statistics by learning the joint distribution of the Gabor function parameters. The joint distribution is then approximated to yield an analytical model of simple-cell receptive fields. Adapting a basis of Gabor functions is found to take an order of magnitude less computation than learning an equivalent non-parameterized basis. Der...
