Figure 4.

Estimation of estimating both shape and appearance changes from 2‐week‐old, 3‐month‐old, 6‐month‐old, and 9‐month‐old to the 12‐month‐old template image (a). From top to bottom row, we respectively show the original subject images, the deformed subject images after applying the learned patchwise appearance‐displacement model, and the deformed subject images after applying both the learned patchwise appearance‐displacement and appearance‐appearance models at 2‐week‐old (b), 3‐month‐old (c), 6‐month‐old (d), and 9‐month‐old (e). It can be observed that both anatomical and appearance discrepancies have been largely decreased after applying these two learned models. [Color figure can be viewed at wileyonlinelibrary.com]
