Fig. 5

The visualization of the segmentation performance of nnUNet, MTnnUNet, MCnnUNet, AAnnUNet, and Ensemble using T2WI, supervised setting. Each row is a different sample from the external test set. The columns from left to right are original T2WI, ground truth, tumor prediction masks from nnUNet, MTnnUNet, MCnnUNet, AAnnUNet, and Ensemble. Colorbar: Shows pixel-wise reconstruction error; higher values indicate greater differences and potential anomalies.
