Abstract
This paper describes an optic flow estimation method based on a discrete wavelet basis analysis. The differential optic flow equation is projected onto analytic wavelets. This gives small local linear systems (3–5 equations) that are solved to find the visual displacement. In this way, we solve the problems of time aliasing and aperture. Since the coefficients of the systems can be computed with filter banks, the estimation of a flow map costs
