Multi-scale classification for electro-sensing

by L. Baldassari and A. Scapin

(Report number 2020-34)

Abstract
This paper introduces premier and innovative (real-time) multi-scale method for target classification in electro-sensing. The intent is that of mimicking the behavior of the weakly electric fish, which is able to retrieve much more information about the target by approaching it. The method is based on a family of transform-invariant shape descriptors computed from generalized polarization tensors (GPTs) reconstructed at multiple scales. The evidence provided by the different descriptors at each scale is fused using Dempster-Shafer Theory. Numerical simulations show that the recognition algorithm we proposed performs undoubtedly well and yields a robust classification.

Keywords: Electro-sensing; weakly electric fish; classifier combination; shape classification; reconstruction
