Examples of label smoothing performed by our proposed method (Algorithm 1). Note that for each image our algorithm performs the smoothing simultaneously on all labels, but here we show a single label in each example for better visualization. In each of the examples presented here, the top image shows the original label obtained via multi-atlas segmentation followed by manual correction of large errors, super-imposed on the T2 image. The lower images show the smoothed label.
