Paper Abstract

This paper presents spatiotemporal statistical models of organ surfaces during human embryonic development, in which size, shape, and topology of organs are dynamically changed. The modeling scheme comprised two steps: (1) each temporal stage of an embryo was statistically modeled, and (2) models between neighboring temporal stages were interpolated. This paper includes optimization of interpolation techniques and a novel method for modeling nested shapes, such as brain and ventricular surfaces. The effectiveness of our method was demonstrated in the context of statistical modeling of a human embryo from the Kyoto Collection.
