Central Symmetry Modelling
1986 (English)In: Proceedings of EUSIPCO-86, Third European Signal Processing Conference / [ed] Ian T. Young, 1986, 883-886 p.Conference paper (Refereed)
A definition of central symmetry for local neighborhoods of 2-D images is given. A complete ON-set of centrally symmetric basis functions is proposed. The local neighborhoods are expanded in this basis. The behavior of coefficient spectrum obtained by this expansion is proposed to be the foundation of central symmetry parameters of the neighbqrhoods. Specifically examination of two such behaviors are proposed: Point concentration and line concentration of the energy spectrum. Moreover, the study of these types of behaviors of the spectrum are shown to be possible to do in the spatial domain.
