Network robustness across affine transform strengths $\gamma$ relative to the range of Appendix Table A2. At a given $\gamma$, we resample each image, drawing affine parameters from uniform distributions modulated by $\gamma$ , such as angle $r\sim \mathcal{U}\left(-\gamma \alpha ,\gamma \alpha \right)$ with $\alpha ={45}^{\circ }$. We test models trained with doubled augmentation (aug) and capacity (cap), comparing $C=4$ Encoders sharing weights, the WLS Decomposer without upsampling, and a $k=32$ Detector. Dice scores are averages over 100 UKBB cross-subject 2D pairs. Shaded areas indicate the standard error of the mean.
