Presence-absence estimation in audio recordings of tropical frog communities

  title={Presence-absence estimation in audio recordings of tropical frog communities},

One non-invasive way to study frog communities is by analyzing long-term samples of acoustic material containing calls. This immense task has been optimized by the development of Machine Learning tools to extract ecological information. We explored a likelihood-ratio audio detector based on Gaussian mixture model classification of 10 frog species, and applied it to estimate presence-absence in audio recordings from an actual amphibian monitoring performed at Yasuni National Park in the… Expand


An intelligent system for estimating frog community calling activity and species richness
Experimental results demonstrate that the proposed intelligent system can significantly facilitate the effort to estimate frog community calling activity and species richness with comparable accuracies. Expand
Detecting Frog Calling Activity Based on Acoustic Event Detection and Multi-label Learning
The proposed method can accurately detect frog calling activity and reflect its relationship with weather variables and statistical analysis is used to reflect the relationship between frogCalling activity (frog abundance and frog species richness) and weather variables. Expand
A toolbox for animal call recognition
The approach has three novel attributes: it works with raw environmental audio, contaminated by noise and artefacts and containing calls that vary greatly in volume depending on the animal's proximity to the microphone, and it adopt bootstrap techniques that can be initiated with little data and refined subsequently.

Screening large audio datasets to determine the time and space distribution of Screaming Piha birds in a tropical forest
Signal processing techniques are developed to reveal the spatio-temporal dynamics of an emblematic bird voice of the neotropical forest: the song of the Screaming Piha (Lipaugus vociferans), suggesting that ScreamingPiha birds tend to avoid non-mature primary forests. Expand
Detecting bird sounds in a complex acoustic environment and application to bioacoustic monitoring
Novel algorithms for the detection of the vocalisations of two endangered bird species are described and it is shown how these can be used in automatic habitat mapping and how they can be employed to support the census of population sizes. Expand
Automatic Classification of a Taxon-Rich Community Recorded in the Wild
This work builds on the multi-instance multi-label framework on bird vocalizations to integrate novel, image-based heterogeneous features designed to capture different aspects of the spectrum, and applied this approach to a taxon-rich habitat that included 78 birds, 8 insect species and 1 amphibian.

Automatic recognition of anuran species based on syllable identification
An unsupervised methodology for anuran automatic identification is proposed, based on the use of a fuzzy classifier and Mel Frequency Cepstral Coefficients, that is able to detect species not presented in the training stage, although they belong to different populations. Expand
Automatic recognition of frog calls using a multi-stage average spectrum
The experimental results demonstrate that the proposed one-level and two-level recognition methods can provide the best recognition accuracies of 91.9% and 94.3%, respectively, compared with other recognition methods based on dynamic time warping (DTW), spectral ensemble average voice prints (SEAV), k-nearest neighbor (kNN) and support vector machines (SVMs). Expand
It is demonstrated that individual identification from bird song can occur even when direct comparison of a particular song type is not possible, and wide applicability radically expands the range of situations in which acoustic individual identification can be used. Expand
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 and predicts the species of groups with 67%-75% accuracy depending upon the partitioning of the training and test data. Expand
