Abstract
A multiresolution analysis (MRA) of L/sup 2/(R/sup 3/), which supports an orthogonal wavelet decomposition and a quadrature mirror filter pyramid algorithm, is the framework for estimating image motion. Instead of the usual iterative pyramid algorithm, a fast, direct derivation of coarse resolution space-time images within the MRA is developed. Two spatio-temporal filtering methods are described. The orientation of surfaces in R/sup 3/ gives robust indication of image motion. However, the alternative method with oriented texture energies in the spatio-temporal image fares poorly when velocities vary.<>
