Example of left ventricle blood-pool segmentation using the proposed approach: a) Blood-pool probability map transferred to the test volume via registration; b) Initial Graph-cut segmentation (first Iteration); c) Segmentation result after refinement based on Intersection-over-Union, small over-segmented region in aorta similar in intensity with blood-pool has been removed; d) Segmentation result after iterative refinement (converged on third iteration); e) Final blood-pool segmentation after refinement using Stocastic Outlier Selection, over-segmented basal slice with distinct shape statistics compared to other slices has been removed.
