Thanks @gdevenyi for the heads up.

I don't use LabelGeometryMeasures much because it doesn't do what most users want, which is estimate cortical surface area.

I was actually looking at this issue recently. If I understand this paper correctly,

https://onlinelibrary.wiley.com/doi/abs/10.1002/1361-6374%28199303%291%3A1%3C6%3A%3AAID-BIO3%3E3.0.CO%3B2-3

it's possible to approximate surface area from a voxel image, if the local geometry is known. What we need though is a filter that computes this only for voxels connected to background.
