ECDS: An effective shape signature using electrical charge distribution on the shape

作者：

Highlights：

• A shape signature ECDS is proposed based on the electrical charge distribution.

• ECDS measures the local amount of charge but computed in a global manner.

• ECDS is articulation insensitive and effective at capturing partial structures.

• The sum of ECDS remains constant during the process of electrical equilibrium.

• ECDS compares well with other descriptors in various shape recognition tasks.
