Sample images of two subjects from the infant database.

<p>We can observe large structural variation across subjects, and also large appearance variation across different images of same subject.</p

Registration via graph shrinkage.

<p>At time t, all the images in the graph (denoted by blue points) are connected to each other by the geodesic path (denoted by blue dash lines). At time t+Δt, all the images are deformed according to their connected images through geodesic paths (denoted by purple dash lines). The deformed images (denoted by red points) become closer to each other and a new graph describing their relationship is generated (denoted by red dash lines).</p
