In the context of inter-subject brain surface matching, we present a parameterization of the cortical surface constrained by a model of cortical organization. The parameterization is defined via an harmonic mapping of each hemisphere surface to a rectangular planar domain that integrates a representation of the model. As opposed to previous conformal mapping methods we do not match folds between individuals but instead optimize the fit between cortical sulci and specific iso-coordinate axis in the model. Experiments on both hemispheres of 34 subjects are presented and results are very promising.
在个体间脑表面匹配的背景下，我们提出了一种受皮质组织模型约束的皮质表面参数化方法。该参数化通过将每个半球表面谐波映射到一个整合了模型表示的矩形平面域来定义。与先前的共形映射方法不同，我们不匹配个体之间的褶皱，而是优化皮质沟与模型中特定等坐标轴之间的拟合。我们展示了对34名受试者两个半球的实验，结果非常有前景。
