Wavelets in Recognition of Bird Sounds
This paper presents a novel method to recognize inharmonic and transient bird sounds efficiently. The recognition algorithm consists of feature extraction using wavelet decomposition and recognition using either supervised or unsupervised classifier. The proposed method was tested on sounds of eight bird species of which five species have inharmonic sounds and three reference species have harmo...
متن کاملBird Species Recognition Using Support Vector Machines
Automatic identification of bird species by their vocalization is studied in this paper. Bird sounds are represented with two different parametric representations: (i) the mel-cepstrum parameters and (ii) a set of low-level signal parameters, both of which have been found useful for bird species recognition. Recognition is performed in a decision tree with support vector machine (SVM) classifie...
متن کاملApproaches to Multiple Concurrent Species Bird Song Recognition
The ability to automatically distinguish one bird species from another based on acoustic recordings of their song has attracted researchers for some time. Existing approaches have concentrated on the case where only a single species is present in a recording. This limits real-world utility of such systems since multiple species of birds frequently sing concurrently and are captured in the same ...
متن کاملA comparison of image processing techniques for bird recognition.
Bird predation is one of the major concerns for fish culture in open ponds. A novel method for dispersing birds is the use of autonomous vehicles. Image recognition software can improve their efficiency. Several image processing techniques for recognition of birds have been tested. A series of morphological operations were implemented. We divided images into 3 types, Type 1, Type 2, and Type 3,...
متن کاملBird Mite Infestation
Mites in the genus Dermanyssus are external parasites of birds, rodents and other mammals. The most common member of this group is the Chicken Mite that infests poultry roosts and wild bird nests. The chicken mite feeds primarily at night when the birds return the nest or roast area. They hide during the day in nearby cracks, crevices and other protected sites. These mites are known to infest h...
