Abstract
This paper proposes a novel shape representation “electric force features”, which is based on electric field theory. This representation has several benefits. First, it is invariant to scale and rigid transform. Second, it can represent complex and ill-defined models because of its physical background. 3D model supposed as charged body, we get the electric field force distribution by placing some testing charges around the 3D model. The force distribution is the feature of the 3D model. Orientation invariance is achieved by calculating the spherical harmonic transform of this distribution. The experiments illuminate that this representation has high discriminating power.
