In this study, the principle that any single-viewpoint catadioptric projection is equivalent to a spherical projection followed by a point projection is explained. Applicability of Gaussian smoothing, line detection and interest point detection using this principle and stereographic projection is investigated. Particularly, Scale Invariant Feature Transform (SIFT) is emphasized.
