Machine Vision for Detecting Water Droplets

Dr. Yan Tong has received a research grant award from the Electric Power Research Institute (EPRI) for "NSF-EPRI: Innovative and Ultra-efficient Evaporators to Realize Cost-effective Desalination”. This project aims to relieve the water-energy-food issues facing the US and the world by substantially reducing the cost of sea water desalination, making it possible to obtain massive freshwater from seawater. Yan's group will develop a fully automatic vision-based technique to detect droplets and to estimate the individual droplet departure frequency and size by non-rigid image registration and onsite-calibration. This vision-based technique is essential to reduce massive data from high-speed optical images to assure a consistent data reduction process.
