Schematic illustration of the hierarchical labeling strategy. In each iteration, only voxels with high segmentation confidence will be selected as additional candidate voxels to reflect the image context information and contribute in the label propagation process in the next iteration. The probability map estimated by the context information will be iteratively updated, and it will be integrated with the probability map estimated from atlases only to produce the final fused probability map. Note that the probability map estimated from atlases needs to be calculated only once.
