Object recognition has been an area of extensive research for a long
time. During the last decades, a large number of algorithms have been
proposed. This is due to the fact that, at a closer look, "object
recognition" is an umbrella term for different algorithms designed for a
wide variety of applications, where each application has its specific
requirements and constraints. This book demonstrates the diversity of
applications and highlights some important algorithm classes by
presenting representative example algorithms for each class.
This book is written in a tutorial style and is therefore suitable as an
introduction into the field of object recognition for interested readers
who are not yet experts. The presentation of each algorithm focuses on
the main idea, which is described in detail, and avoids extensive usage
of mathematics. Graphic illustrations of the algorithm flow facilitate
understanding.
The algorithms presented are classified according to the following
categories: global approaches, transformation-search-based methods,
geometrical model driven methods, 3D object recognition schemes,
flexible contour fitting algorithms and feature-based methods. Typical
example algorithms are presented for each of the categories.
