A close-up view of a slice from the T1-weighted dataset from the validation set. Left: the original slice; Right: segmentation results from the automated framework and the human observer are overlaid. True positives (TP) are green; false positives (FP) are yellow, and false negatives (FN) are light blue. Here, the expert omitted this slice, but the framework detected a soft palate region, which was considered as false positives. However, it cannot be claimed that the network detection is wrong, since anatomically it is in the correct position, and the expert had probably rejected the slice due to a relatively low size of the soft palate region
