Howto get a centroid of a section in a slice?

@jumbojing

Lassoan教授，好吧。。。我想出来个笨拙的解决方案：

Prof.Lassoan, okay. . . I came up with a clumsy solution:

不过这个解决方案有个问题：就是提取的点和点之间的距离不均匀。。。谁有好办法呢？

However, there is a problem with this solution: the distance between the extracted points is not uniform. . . Who has a better solution?

Such As Weighted when calculating the average?

I want to weight the centroid obtained above by the reciprocal of voxel (CT value), how to do it?
