Visualization of the predictions of the landmark coordinate regression model on the mid-sagittal slice of the T2 sequence. Green (ground-truth landmark) and red (model-predicted landmark) had a mean absolute error of 1.14 mm in this example. Since the model is constrained to generate exactly 5 landmarks, they correspond to L1/L2, L2/L3, L3/L4, L4/L5, and L5/S1
