Detecting lobar fissures is elementary ingredient of segmentation and construction of lung lobe. This paper presents an efficient algorithm for automatic segment lobar fissures. A local adaptive segmentation identifies linear structures of lung CT image. Based on skeletons of the linear structures, the endpoints of the fissures are attained. The dynamic programming detects the fissure between the endpoints. The validation of the proposed method is proved through the experiments.
