         Sphericity is particularly sensitive to the resolution of the mesh, as it directly impacts the accuracy of surface area and volume calculations.
-        Indeed, since the mesh is generated from voxel-based 3D volume data, the discrete nature of the voxels leads to pixelation effects that reduce the precision of sphericity measurements.

         Higher resolution meshes may mitigate these errors but often at the cost of increased computational demands.
