Positive curvature has been a frequent subject in Riemannian geometry.

Then, make use of the positive curvature extreme points which correspond to each silhouette segment, to combine fine silhouette segments. So we can obtain the silhouette, which can represent limbs of human body.

然后，利用每个轮廓片段对应的正曲率极值点将细小轮廓片段进行合并，从而获得能够单独表示人体肢体的轮廓。
