Interpretable Model Based on Pyramid Scene Parsing Features for Brain Tumor MRI Image Segmentation

Figure 6

Four groups are selected from the visualization results of PSPNet for analysis, including the ones with poor segmentation performance (a, b) and the ones with good segmentation performance (c, d). Among them, , , , and , respectively, represent the visualization of the pooling results under the four feature scales, while PSP-Features represents the fusion results of the four pooling scales in PSPNet.
