Abstract
This paper concerns the robustness of phase information for measuring image velocity and binocular disparity, its stability with respect to geometric deformations, and its linearity as a function of spatial position. These properties are shown to depend on the form of the filters used and their frequency bandwidths. The authors also discuss situations in which phase is unstable, many of which can be detected using the model of phase singularities (see Image Vis. Comput. (UK) vol.9, no.5, p.333-7 (Oct. 1991))
