Multi-Frequency Synthesis of VLBI Images Using a Generalized Maximum Entropy Method
نویسنده
چکیده
A new multi-frequency synthesis algorithm for reconstructing images from multi-frequency VLBI data is proposed. The algorithm is based on a generalized maximumentropy method, and makes it possible to derive an effective spectral correction for images over a broad frequency bandwidth, while simultaneously reconstructing the spectral-index distribution over the source. The results of numerical simulations demonstrating the capabilities of the algorithm are presented. PACS numbers: 95.55.Jz, 95.75.Kk, 95.75.Mn DOI: 10.1134/S1063772908120019

Experience of High Resolution Vlbi Imaging Using Generalized Maximum Entropy Method
The generalized maximum entropy method (GMEM) is a special modification of the standard maximum entropy method (MEM) which seeks solutions in the space of complex functions. In this work a reduced version of the GMEM intended for reconstructing real images with positive and negative values is used. As compared with the standard MEM, intended for the reconstruction of only non-negative images, t...
متن کاملPlant Classification in Images of Natural Scenes Using Segmentations Fusion
This paper presents a novel approach to automatic classifying and identifying of tree leaves using image segmentation fusion. With the development of mobile devices and remote access, automatic plant identification in images taken in natural scenes has received much attention. Image segmentation plays a key role in most plant identification methods, especially in complex background images. Wher...
متن کاملDeconvolution of astronomical images using the multiscale maximum entropy method
— Following the ideas of Bontekoe et al. who noticed that the classical Maximum Entropy Method (MEM) had difficulties to efficiently restore high and low spatial frequency structure in an image at the same time, we use the wavelet transform, a mathematical tool to decompose a signal into different frequency bands. We introduce the concept of multi-scale entropy of an image, leading to a better ...
متن کاملA Generalized Approach to Word Segmentation Using Maximum Length Descending Frequency and Entropy Rate
In this paper, we formulate a generalized method of automatic word segmentation. The method uses corpus type frequency information to choose the type with maximum length and frequency from “desegmented” text. It also uses a modified forward-backward matching technique using maximum length frequency and entropy rate if any non-matching portions of the text exist. The method is also extendible to...
متن کاملFault diagnosis of gearboxes using LSSVM and WPT
This paper concentrates on a new procedure which experimentally recognises gears and bearings faults of a typical gearbox system using a least square support vector machine (LSSVM). Two wavelet selection criteria Maximum Energy to Shannon Entropy ratio and Maximum Relative Wavelet Energy are used and compared to select an appropriate wavelet for feature extraction. The fault diagnosis method co...
