Acknowledgment
I do not have enough words to thank Professor Kim Dong-Yoon. You are
the main reason for whatever I achieved so far. Thank you so much for all
the trust, fatherly advice and encouragement; thank you so much for the
thoughtfulness and kindness you showed me. I will never forget what you
did. I would also like to sincerely thank Professor Wee Yung-chul for
offering me such a wonderful chance to work with you. It was a great
privilege to have been advised and guided by a brilliant professor like
yourself. You assisted and taught me a lot and I so much appreciate your
brains. I also thank Professor Shin Hyun-Joon for always telling me that I
can do it, keeping my spirits high. For sharing your experience and being
patient with whoever I was in those moments I worked with you. I
appreciate your understanding, the ideas you generate and superb
comments you give. Thank you so much Professor Lee Yun-Jin, for being
so kind and for quenching my thirst of the basic concepts in computer
graphics. I cherished your class and the knowledge I acquired helped me to
answer some basic questions when doing this research.
My acknowledgement will never be complete with out mentioning the
accompany I had from Legesse Zerubabel. You were always there
whenever I needed some one to talk to, sharing my burdens and worries. I
thank Jonghyuk Kim and all the other members of the visual computing lab
for being so wonderful to me and lending a hand whenever I needed one. I
would also like to thank Mee-yeon Woo for taking care of my issues with
the department. You were so caring and helpful. Special thanks to Chan,
Anatolly and all my Ethiopian and Korean friends for making my stay at
Ajou so much fun and easy. Finally, I would not have reached here if it was
not for the life transforming scholarship I got from the Institute of
Information Technology Advancement and Ajou University. Thank you.
Praise be to God!
