BUFAR is an algorithm designed to provide a detailed analysis about the foraging behavior in grazing cattle. It analyzes a sound recording to recognize and characterize jaw movements and foraging activities. First, detection and classification of jaw movements (chews (c), bites (b), and composed chew-bites (x)) are performed. Then, foraging activities (grazing and rumination bouts) are recognized by considering features of previously recognized jaw movements.
This web-demo requires an audio recording file as input (download examples). The input sound must be a one channel (mono, 16-bit, 44.1 kHz) WAV file up to 15 min in length. Clic “Choose file”, browse for the file to upload, click Upload, and then click Submit. If no file is provided, the example file will be loaded by default. The output are two TXT files:
- Timestamps and labels corresponding to foraging activities (rumination and grazing bouts). Noise will be assigned when no activity is identified.
- Timestamps and labels corresponding to jaw movements (c, b or x).
Both input (sound signal) and output (timestamps and labels) files can be imported in Audacity to get a graphical view of the recognition.
