Look out for:
• the basic concepts of optical flow, and its limitations.
• the idea of a focus of expansion, and how it leads to the possibility of “structure from motion.”
• how motion stereo is achieved.
• the important status of the Kalman filter in motion applications.
• the ways in which invariant features may be used for wide baseline matching.
Note that this introductory chapter on 3-D motion leads to important methods for performing ...
