Paper Abstract

A distortion-invariant feature is proposed in this paper, which is based on the normalization polar coordinates of closed nohole space targets' boundary. In order to utilize this proposed feature to recognize distortion targets in 2-D, a dynamic compensation matching method for the target's polar coordinates is put forward. Computer simulation shows this approach has the best distortion-invariant recognition ability.
