Bookmark not defined. Table 3: Various Quality Metrics for Ultrasound Image This graph theory uses graphs were vertices phd thesis in engineering points are collected phd thesis in engineering connected to the phd thesis in engineering which are also known as lines. In graph theory, some are directed graph where lines have a single arrow which denotes in specific direction alone.

In some other graph, edges are not located which is it does not have any edges or sometimes lines may overlap but is have the same vertex alone World. Mathigon, Some other applications of graph theory are minimizing traffic congestion, creating road network, evaluating the impact of environmental data and so on. Among different segmentation methods, graph theoretical approaches have many useful features in practical applications, phd thesis in engineering. The graph-based image segmentation is a highly effective and cost-effective way to perform image segmentation.

But, it not been implemented in an efficient manner. Additionally, the previous research fails to provide versatile graph-based algorithms for a broad range of practical applications Peng et al. Furthermore, the numerous applications and a huge amount of medical image data phd thesis in engineering sophisticated software that combines high-level graphical user interfaces as well as that each of them represents a meaningful object of interest in the image.

Furthermore, compare the efficiency and effectiveness of various graph-based image segmentation algorithms in medical image classification. These methods have generated significant interest in the imaging community. The study focuses on the following properties: minimal spanning trees, normalized cuts, Euler graph, and Iterated Graph cut.

The focus of segmentation is to simplify or modify the representation of an images. In specific, image segmentation is to simplify the representation of a picture the same label share certain visual characteristics or features.

To segment the image using two different kinds of local neighborhoods in constructing the graph, and illustrate the results with both real and synthetic images, phd thesis in engineering. To analyze the quality of the image by using various segmented results, phd thesis in engineering.

This used to analyze the efficiency and accuracy of the segmentation process. The three types of image features in which are interested as points, edges, and lines.

Thus, this theory is becoming a perfect representation of image processing and analysis. Moreover discussed the previous studies related to various methods Image cluster, analysis, segmentation, wavelet transform and phd thesis in engineering extraction and application remote sensing, medical application, computer vision. Chapter III is Research Methodology, which recognizes the research questions.

It explains procedures and the objectives to carry out the research. A detailed description of all the research methods including sampling procedure, data collection and type of analysis to be used for the data is elaborated in this section. Chapter IV is discussed the experimental methods. Further, phd thesis in engineering, analyzed the performance of proposed approach using image quality analysis approach.

Chapter V discussed the simulation results using Matlab software with various images like Computed Tomography CTMagnetic Resonance MRUltrasounds US images.

Finally, Chapter VI discussed findings and conclusion of this research. Graph theory is phd thesis in engineering of the recent research areas of modern mathematics which has witnessed a magnificent growth due to some applications in computer and communication, molecular physics and chemistry, social networks, biological sciences, computational linguistics, phd thesis in engineering, and in other numerous areas.

In graph theory, one of the extensively researched branches is domination in the graph Haynes et al. In recent years, graph theory exhibits a spectacular growth has been witnessed due to its wide range of applications in classical algebraic problems, optimization problems, combinatorial problems, computational problems, etc.

This is mainly due to the rise of some new parameters that has been developed from the basic definition of domination. This structural arrangements of various Shirinivas et al. This problem leads to the concept of Eulerian Graph. InA. F Mobius gave the idea of a complete graph and bipartite graph networks or circuits. InThomas Gutherie found the famous four color problem. In the year ofThomas. Kirkmanand William R. Hamilton studied cycles on polyhydra and invented the concept called Hamiltonian graph by studying trips that visited certain sites exactly once.

Even though the four color problem was invented, it was solved only after a century by Kenneth Appel and Wolfgang Haken. This time is considered as the birth of Graph Theory, phd thesis in engineering. Graph theory is a branch of discrete mathematics where mathematics and computer science, graph theory is the study of graphs which are mathematical structures used to model pairwise relations between objects Singh and Vandana For solving a wide range of problems, graphs are widely used because it gives an intuitive manner before presenting formal definition.

To analyze the graph theory application two problem areas are considered. Classical problem 2. Problems from applications In graph theory, the basic classical problem is defined with the help of the graph algorithms. Graph drawing Nishizeki et al. In this sets, each edge joins a pair of nodes where graphs are represented graphically by drawing a dot for every vertex, and drawing an arc between two vertices if they are connected phd thesis in engineering an edge through the use directed arrow drawing arrows.

Every edge can give a real value which means that a graph is extended with a weight function. In the case, when a graph presents set of nodes, the weight function is a length of every mode phd thesis in engineering is stated as a weighted graph. A graph G is a mathematical structure used to model pairwise relations between objects from a certain collection.

A graph in this context refers to a nonempty set of vertices and a collection of edges that connect pairs of vertices. The set of vertices is usually denoted by V G and the set of edges by E G. The edges can be directed or undirected; it depends on the example.

A graph with all directed edges is called directed graph. Otherwise it is called undirected. In a proper graph, which is by default undirected, a line from point u to point v is considered to be the same thing as a line from point v to point u.

In a digraph, phd thesis in engineering, short for a directed graph, the phd thesis in engineering directions are counted as being distinct arcs or directed edges. If a graph G is undirected, then there is no distinction between the two vertices associated with each edge. In a directed graph its edges may be directed from one vertex to another. Graphs are extremely powerfull and yet flexible tool to model. Graph theory includes many methodologies by which this modeled problem can be solved.

Authors of the paper have identified such problems, some of which are mentioned in this paper. Shirinivas et al. This information is important when looking at breeding patterns or tracking the spread of disease, parasites and to study the impact of migration that affects other species. Graph theoretical concepts are widely used in Operations Research. For example, the traveling salesman problem, the shortest spanning tree in a weighted graph, obtaining an optimal match of jobs and men and locating the shortest path between two vertices in a graph.

It is also used in modeling transport networks, activity networks, and theory of games. The network activity is used to solve a large number of combinatorial problems. Pavan and Pelillo presented a method in general and it does not but weak edges might require combination with region-based approaches. In addition, will also need scale-space texture analysis; in particular, adding textures characteristics to the feature vectors describing polygons and their pairwise relations.

Sarsoh et al. This study faced two issues one is, in few cases face images for more than one person are lied in the same cluster and the second one is, face images of some person were partitioned into two clusters. The future study must be conducted to remove this problem. Elmasry et al. For better accuracy additional features such as shape, phd thesis in engineering, texture is also needed to be used.

This study gave only a concept of segmentation of live CT images. Peng et al.
