A Real Time Imaging System For Assessment And Control Swine Thermal Comfort , Bin Shao

Retrospective Theses and Dissertations

A real-time bioimaging system was developed to detect movement of group-housed pigs and to classify thermal comfort state of the pigs based on their resting patterns. This dissertation describes the background, theory, image features selection and analysis, image classification techniques, system architecture, and system performance with artificial and live pigs.;The system is based on the bioimaging control method: using animal's thermal behavior as the ultimate biosensor that is used to reflect animal thermal comfortable levels. An automated real time image processing and control system is developed that monitors animal behavior and adjusts external devices according to the image ...
