| Abstract | ||
| Biometrics is defined as the science of recognizing human by using their personal biological characteristics, for example voice, fingerprint and signature. Biometrics approach has then been implemented for recognizing animal for the purpose of biological and ecological research and development. Due to the research on animal based recognition is still in infancy, so in this study, the evaluation on the effectiveness of the audio based biometric system approach to the bioacoustics identification system is experimented. Bioacoustics based on frog call in order to identify the frog species is employed in this study. Consequently, the well-known features used in audio based biometric system i.e. Mel-frequency Cepstral Coefficients (MFCC) is experimented as features for the frog bioacoustics based identification system. For the classification process, performances of Support Vector Machine (SVM), k-Nearest Neighbor (k-NN), Local Mean k Nearest Neighbor (LMkNN) and Fuzzy k-NN (FkNN) classifiers have been compared in this study. The performances of the biometric system and the frog bioacoustics system based on the proposed classifiers are evaluated. The best performance has been observed using FkNN classifier with the accuracy of 97% for the frog bioacoustics identification system and 93.38% for the biometric speaker identification system with 20 training data. | ||
