Interpretation of Image Flow: A Spatio-Temporal Approach

A general formulation is described for the interpretation of image flow. In the framework of this formulation, computational methods have been derived for image flow interpretation for many important cases, including simple cases of nonrigid and nonuniform motions. It is possible to derive computational methods for other situations not considered explicitly. The formulation is general in that it is applicable to any situation provided that the scene geometry, the scene transformation, and the image flow are all 'smooth' or analytic. >
