About the Author
Shin Shi is a member of the Digital Art Lab at Shanghai Jiao Tong University.
When he built his first robot at the age of fourteen in 2005, he became interested
in the field of computer vision. Over the last two years, he created a real-time face
recognition attendance system using Emgu CV at Huazhong University of Science and
Technology. He obtained a B.E. in Software Engineering from HUST and is currently
an M.S. candidate in DA Lab from SJTU. Now he is focusing on the field of computer
graphics, such as creating physics-based simulations and the use of animation.
Foremost, I would like to give a very special thanks to my soul
mate, Licheng Yin, for his invaluable support and patience. And I
would like to express my sincere gratitude to Prof. ZP Qin, for his
motivation and immense knowledge.
Last but not least, I would like to thank my family for supporting me
spiritually throughout my life.
