1. A method for segmentation of a vessel, the method comprising:

  • extracting a centerline for a vessel represented in medical imaging data representing a patient, the extracting being a function of a cost term;

    calculating the cost term as a function of similarity of patches of the medical imaging data to machine-learned appearance patterns at multiple scales relative to the medical imaging data, the cost term indicating membership as in the vessel or not in the vessel of different locations for the patches;

    segmenting the vessel as represented in the medical imaging data, the segmenting being a function of the centerline; and

    generating an image of the vessel segmented from the medical imaging data.
