Table 2 Automatic detection results for different related and the proposed method

From: Establishing the fundamentals for an elephant early warning and monitoring system

Method Detection rate (%) False-positive rate (%)
Hao et al. [44] 78.6 78.6
Venter and Hanekom [28] 85.7* 14.2*
Proposed method without signal enhancement 88.2 24.4
Proposed method with signal enhancement 88.2 13.7
  1. Signal enhancement strongly influences detection performance, especially the false-positive rate
  2. * Results by Venter and Hanekom [28] are not directly comparable as they were obtained for a different (smaller) dataset with fewer rumbles
