Online monitoring of oil film using electrical capacitance tomography and level set method.
TLDR
A distance regularized level set evolution formulation is extended to image two-phase flow online using an ECT system, a narrowband image filter is defined to eliminate the influence of artifacts, and considering the continuity of the oil distribution variation, the detected oil-air interface of a former image can be used as the initial contour for the detection of the subsequent frame, making it possible for real time tracking.
