Global Methods for Image Motion Analysis

To My Parents iv ACKNOWLEDGEMENTS I wish to thank my advisor Bob Hummel for his advice and guidance, in particular for teaching me the mathematical approach to solving problems in vision, and for showing me how to present the results. I would like to thank Stephane Mallat for introducing me to the eld of visual motion analysis and for his encouragement and support. The experience with Rob Kelly and his group at Grumman and the support that they provided were valuable. Ken Perlin's interest in my w ork, his encouragement, and cheerfulness inspired me to tide many a hard day. I w ould like to thank all my friends for all the inspiration, the encouragement, and all the good times we had together.
