In recent years, there has been a growing interest in the fields of pattern recognition and machine vision in academia and industries. New theories have been developed, with new design of technology and systems in both hardware and software. They are widely applied to our daily life to solve real problems in such diverse areas as science, engineering, agriculture, e-commerce, education, robotics, government, medicine, games and animation, medical imaging analysis and diagnosis, military, and national security.

The foundation of all this field can be traced back to the late Professor King-Sun Fu, one of the founding fathers of pattern recognition, who, with visionary insight founded the probably true to say that most people are affected by, or use applications of pattern recognition in daily life.

Today, on the eve of 25th anniversary of the unfortunate and untimely passing of
Professor Fu, we are proud to produce this volume of collected works from world
renowned professionals and experts in pattern recognition and machine vision, in honor and memory of the late Professor King-Sun Fu. We hope this book will help promote further the course, not only of fundamental principles, systems and technologies, but also its vast range of applications to help in solving problems in daily life.
