Scale-Space Phase Singularitiester instability in that the phase contours are nearly horizontal and not vertical as desired. Because some geometric deformation is expected between left and right binocular views, or between frames of an image sequence, this instability, if not detected, is bound to cause poor measurements.

It is therefore natural to begin with a discussion of image formation, the ways in which properties of the world are manifested in images as a function of time and space.

Velocity-Specific Representationon the particular approach, the main objectives of such filtering are noise reduction and/or the isolation of different types of image structure (e.g. zero-crossing contours, or different scales for coarse-fine analysis). More recently, it has been recognized that the filters themselves can be tuned
