This paper proposes a new characteristics measurement technique for a 3-D surface, based on multiple spatial filtering, and also shows qualitative and quantitative analysis comparing with conventional differential geometric characteristics with experiments. At the end of the paper, we study the generalization of filtering technique for characteristics measurement of curvs and surfaces.
