Motion and Logmap

Special types of global motion patterns consisting of circular, radial or spiral flow fields can easily be detected if the complex logarithmic transformation is applied on the input pattern (Neumann, H., Bayerl, P.: Bewegungswahrnehmung - die Illusion der Realität. Nervenheilkunde, 22, 322-324, 2003).
logpolar_motion
Motion patterns evolving from self-motion - and therefore mainly consist of radial flow - can easily be detected with such a representation (Seifart, F., Bayerl, P., Neumann, H.: The role of log polar mapping for heading estimation and heading representation in a model of motion integration. TWK'03).
