| gaussian mixture model classification of odontocetes in the southern california bight and the gulf of california. | a method for the automatic classification of free-ranging delphinid vocalizations is presented. the vocalizations of short-beaked and long-beaked common (delphinus delphis and delphinus capensis), pacific white-sided (lagenorhynchus obliquidens), and bottlenose (tursiops truncatus) dolphins were recorded in a pelagic environment of the southern california bight and the gulf of california over a period of 4 years. cepstral feature vectors are extracted from call data which contain simultaneous ov ... | 2007 | 17407910 |
| classification of echolocation clicks from odontocetes in the southern california bight. | this study presents a system for classifying echolocation clicks of six species of odontocetes in the southern california bight: visually confirmed bottlenose dolphins, short- and long-beaked common dolphins, pacific white-sided dolphins, risso's dolphins, and presumed cuvier's beaked whales. echolocation clicks are represented by cepstral feature vectors that are classified by gaussian mixture models. a randomized cross-validation experiment is designed to provide conditions similar to those fo ... | 2011 | 21303026 |
