摘要:In this talk, we will present the fundamental structure equations, invariant geometric flow for curves and hypersurfaces under affine-related transformation. On the other hand, we will show some applications of affine-related invariants in computer vision and fractals.

The centro-affine invariants are applied to develop an invariant algorithm to match features of objects appearing in images. A point-set similarity model (PSM) is introduced, which provides a new elastic point set registration frame by using similarity invariant signature curves.
