Ablation Study Table 2 contains a controlled ablation of encoder capacity and working batch size across a fixed schedule of 15 epochs, and a definite trend is apparent as follows: the backbone capacity is the dominant factor in overlap quality, with EfficientNet-B3 achieving the highest Dice at batch size 16 (0.77), followed by EfficientNet-B0 (0.75), ResNet50 (0.73), and ConvNeXt-Tiny (0.67).
