ABSTRACT
This chapter identifies the globular foam’s boundary automatically. Foams were formed by trapping pockets of gas in a liquid or solid. Firefighting foams were produced by liquid foam solution using a generating device. The surfactant in the foam’s film would keep a relative balance of the foam. Traditional macroscopic parameters on fire-fighting foam included foam expansion and drainage time. Foam expansion meant the ratio of foam’s volume to foam solution’s volume. The foam’s structure graphs could be captured by a microscope device. The globular foam’s boundary could be identified by modified particle analyzer. Circumference of a circular or globular object was the linear distance around the foam’s edge. Foam number per unit area was expressed in square millimeter. This number changes with foam’s breakup. Most of the globular foams were identified automatically. Some of the nonglobular foams were identified manually.
