An oriented flux symmetry based active contour model for three dimensional vessel segmentation

摘要: This paper proposes a novel approach to segment three dimensional curvilinear structures, particularly vessels in angiography, by inspecting the symmetry of image gradients. The proposed method stresses importance simultaneously considering both gradient with respect structure center, and antisymmetry object boundary. Measuring remarkably suppresses disturbance introduced rapid intensity changes along structures. Meanwhile, helps locate are evaluated based on notion oriented flux. By utilizing aforementioned information, an active contour model is tailored perform segmentation. On one hand, exploiting symmetric pattern observed at centers, contours expand structures even through there exists fluctuation other measuring conveys strong detection responses precisely drive boundaries, as well avoiding leakages. capable delivering promising segmentation results. validated experiments using synthetic data real vascular images different modalities, comparison two founded published methods for
