Abstract

A method for the detection of bubble contours in images of subcooled boiling in microgravity is proposed. The method refines an initial, rough contour approximation obtained from conventional background subtraction. This refinement entails the warping of an elliptical ring image region into a polar image, where bubble contour detection becomes simpler. The proposed method exhibits robustness to a wide variety of visual phenomena that typically hinder the detection of bubble contours. This is achieved by the grouping of continuous image edges. A ground truth annotated data set is provided that enables the quantitative and comparative evaluation of the proposed methods.
