Preface 
 
In the machine vision field, the theory has been studied for many decades. Fortunately, 
the computer technique is also developed rapidly simultaneously. Recently, these theories 
of machine vision have been realized practically in variety applications. The machine vision 
system consists of the optics, electronics, machinery and the computer information 
technology systematically. The technique is applied widely industrially including vision 
servoing trajectory motion control, optical measurement and automatic examination, pattern 
identification and system monitoring and so on. The advantages of the vision system are the 
non-contact measurement, versatility, cost effectiveness, and practicality. Therefore, the 
machine vision technology can be investigated and studied enthusiastically to improve the 
industrial development and human engineering. 
In the field of machine vision, there are many technique books about introducing the 
fundamental theory of vision. But there is not a book about how to employ the vision theory 
in the market conditions for students or researchers who want to realize the technique of 
machine vision. It is meaningful to employ the vision theory to the practical application, and 
the vision theory can also be employed originally by different field researchers. 
I am pleasant that the book consists of 10 chapters by different fields about vision 
applications. The authors in chapters are excellent in their research fields. It is honored to 
collect the 10 chapters that depict the multiplicity of the vision theory by the authors. For the 
readers, you can select some kinds of applications you are interesting in this book, and to 
study the detailed contents in each chapter. This book collects the main studies about 
machine vision currently in the world, and has a powerful persuasion in the applications 
employed in the machine vision. The contents, which demonstrate that the machine vision 
theory, are realized in different field. For the beginner, it is easy to understand the 
development in the vision servoing. For engineer, professor and researcher, they can study 
and learn the chapters, and then employ another application method. 
The goal of this book is to introduce the visional application by excellent researchers in 
the world currently and offer the knowledge that can also be applied to another field
