- •
Hybrid methods for age consistent segmentation in premature neonates are proposed.
- •
Approaches combine atlas- and patch-based methods for age-specific tissue labeling.
- •
Validation against manual tracing over a large age range was conducted.
- •
Results show significant improvement compared to conventional age-specific methods.
