Research Precision livestock farming

Precision livestock farming consists in the application of information and communication technologies to continuously monitor each animal in a farm, in a fully automatic way. Retrieved information helps in management to fulfil the basic health and welfare requirements of livestock, to early detect problems, and to improve the efficiency of production systems. Many physical variables can be monitored using sensors like microphones, thermometer, accelerometers, inertial measurement units, among others. Data provided by the sensors need to be analyzed by ad-hoc algorithms to process data and retrieve the information to help in the management decisions.
The aim of this research line is to design, develop and implement algorithms based on signal processing and pattern recognition techniques for: i) animal foraging monitoring and ii) heat detection.
