An improved local morphology fitting active contour model with weighted data term is proposed in this paper for automated segmentation of the vascular tree on 2-D angiogram. In the original local morphology fitting model, morphological fuzzy minimum and maximum opening are adopted to approach the background and vessel object, separately. The structuring elements used in the morphology operator are linear ones, and their scale and orientation are computed from the image. The energy of the active contour model is minimized through a level set fra...
