Abstract
It is proved that local moments are related to their surface fitting c oefficients by a linear transform, and by this the surface-fitting-bas ed-feature extraction is converted into the computation of 2D local mo ments. A NPT recursive method is proposed to compute 2D local moments quickly and then to efficiently implement surface fitting. The new met hod has a novel advantage that its computational complexity for both 2 D local moment computation and surface fitting is independent of the m ask size, which much efficiently speed up the feature extraction.
