[Lung boundary detection method based on binary morphology theory].
Li Lü, Yixin Ma, Huawei Wu · PubMed · 2010
A method is presented in this paper which processes the human chest CT image with binary morphology theory, then marks and searches each connected domain to find chest contour and boundaries of lung and esophagus. Comparing with original CT image, the extracted boundaries have sufficient accuracy and human eyes cannot distinguish the error.
