A Multi-pattern Matching Algorithm Based on WM Algorithm
نویسندگان
چکیده
The research on the algorithms of pattern-matching is an important subject in the field of computer study. The algorithms can range from single-pattern matching and multipattern matching algorithms to extended characters matching and regular expression. Among the many multi-pattern matching algorithms, AC algorithm and WM algorithm would be the two most classical algorithms, but these two algorithms have their obvious shortcomings. The multi-pattern matching algorithm proposed in this paper filtrates the texts which do not match correctly with the idea of jumping ahead of the WM algorithm firstly, and then matches the text with the idea of rapidly matching of the AC algorithm which can improve the efficiency of the algorithm. Keywords-Multi-pattern Matching; AC; WM

An Automated MR Image Segmentation System Using Multi-layer Perceptron Neural Network
Background: Brain tissue segmentation for delineation of 3D anatomical structures from magnetic resonance (MR) images can be used for neuro-degenerative disorders, characterizing morphological differences between subjects based on volumetric analysis of gray matter (GM), white matter (WM) and cerebrospinal fluid (CSF), but only if the obtained segmentation results are correct. Due to image arti...

متن کاملA New RSTB Invariant Image Template Matching Based on Log-Spectrum and Modified ICA
Template matching is a widely used technique in many of image processing and machine vision applications. In this paper we propose a new as well as a fast and reliable template matching algorithm which is invariant to Rotation, Scale, Translation and Brightness (RSTB) changes. For this purpose, we adopt the idea of ring projection transform (RPT) of image. In the proposed algorithm, two novel s...

متن کاملOn the inverse maximum perfect matching problem under the bottleneck-type Hamming distance
Given an undirected network G(V,A,c) and a perfect matching M of G, the inverse maximum perfect matching problem consists of modifying minimally the elements of c so that M becomes a maximum perfect matching with respect to the modified vector. In this article, we consider the inverse problem when the modifications are measured by the weighted bottleneck-type Hamming distance. We propose an alg...
