Segmentation of MS lesions using entropy-based EM algorithm and Markov random fields

引用

Journal of Biomedical Science and Engineering 2011年第8期4卷 552-561页

作者： Ahmad Bijar Mahdi Mohamad Khanloo Antonio Penalver Benavent Rasoul Khayati Department of Biomedical Engineering Shahed UniversityTehranIran Department de Estadística Matemáticas e InformáticaUniversidad Miguel HernándezElcheSpain

This paper presents an approach for fully automatic segmentation of MS lesions in fluid attenuated inversion recovery (FLAIR) Magnetic Resonance (MR) images. The proposed method estimates a gaussian mixture model with three kernels as cerebrospinal fluid (CSF), normal tissue and Multiple Sclerosis lesions. To estimate this model, an automatic Entropy based EM algorithm is used to find the best estimated Model. Then, Markov random field (MRF) model and EM algorithm are utilized to obtain and upgrade the class conditional probability density function and the apriori probability of each class. After estimation of Model parameters and apriori probability, brain tissues are classified using bayesian classification. To evaluate the result of the proposed method, similarity criteria of different slices related to 20 MS patients are calculated and compared with other methods which include manual segmentation. Also, volume of segmented lesions are computed and compared with gold standard using correlation coefficient. The proposed method has better performance in comparison with previous works which are reported here.

Wavelets and Continuous Wavelet Transform for Autostereoscopic Multiview Images

引用

Journal of Electrical Engineering 2016年第1期4卷 19-23页

作者： Vladimir Saveljev Dept. of inform. Display Engineering Hanyang University Seoul 133-791 Korea Imaging Media Research Center KIST Seoul 136-791 Korea

Recently, the reference functions for the synthesis and analysis of the autostereoscopic multiview and integral images in three-dimensional displays were introduced. In the current paper, we propose the wavelets to analyze such images. The wavelets are built on these reference functions as on the scaling functions of the wavelet analysis. The continuous wavelet transform was successfully applied to the testing wireframe binary objects. The restored locations correspond to the structure of the testing wireframe binary objects.

Moving analogy target is a key component of the performance testing system in TV tracking equipment. A new method is provided to produce the moving analogy target whose motion speed, track, contrast and size can be varied. The video signal transformed by video switching card is used to test the performances of the electronic box of TV tracking equipment. These performances include minimal tracking contrast, minimal size of tracking target, maximal tracking speed and capture time.

A Comparative Analysis between BPMN and SPEM Modeling Standards in the Software Processes Context

引用

Journal of Software Engineering and Applications 2012年第5期5卷 330-339页

作者： Carlos Portela Alexandre Vasconcelos Antonio Silva Ariane Sinimbú Elder Silva Maurício Ronny Wallace Lira Sandro Oliveira Centro de informática Universidade Federal de PernambucoRecifeBrazil Instituto de Ciências Exatas e Naturais Universidade Federal do ParáBelémBrazil

The main objective of this paper is to analyze the representativeness of the SPEM (Software Process Engineering Metamodel Specification) and the BPMN (Business Process Modeling Notation) standards in the software processes modeling context. To perform this analysis, it was adopted a standard structure to define a software process based upon a process ontology. Then, the SPEM and BPMN standards notations and their semantically corresponding elements in the default process were identified. This mapping also includes components of the CMMI-DEV (Capability Maturity Model Integration for Development) and MR-MPS (Reference Model for Software Process Improvement) quality models. This was necessary to assist in the mapping evaluation through a case study which models the best practices of these quality models. Finally, we carried out an analysis of these standards through specific characteristics considered necessary to model and to represent software processes.

Numerical Mathematics A Journal of Chinese Universities(English Series) 2002年第2期11卷 161-178页

作者： Zhao Shuangsuo(赵双锁) Zhang Guofeng(张国风) Dept. of inform. and Comput. Sci. The Second Northwest University for Nationalities Yinchunan 750021 PRC Dept. of Math. Lanzhou University Lanzhou 73000 PRC

This paper presents a class of r-point (r+1)st-order A-stable one-block methods with damping at the infinite point (DIAOB r,r+1 ). Under the conditions of the same order, A-stability, operation count (at each iterative step) and storage space are the same as the methods in , the methods in the paper improve the stability in a neighborhood at the infinite point. And, by using the OOPI method , it possesses much faster rate of convergence for solving systems of nonlinear equations produced by the DIAOB r,r+1 .

关键词： one-block method, stiff problem, A-stability, damping at infinite point.
