| Label () | |
| Default constructor for a label. | |
| Label (std::vector< int > vertices, std::vector< float > values) | |
| Construct a Label from the given vertices / voxel numbers and values. | |
| Label (std::vector< int > vertices) | |
| Construct a Label from the given vertices / voxel numbers. | |
| std::vector< bool > | vert_in_label (size_t surface_num_verts) const |
| Compute for each vertex of the surface whether it is inside the label. | |
| size_t | num_entries () const |
| Return the number of entries (vertices/voxels) in this label. | |
Public Attributes | |
| std::vector< int > | vertex |
| vertex indices for the data in this label if it is a surface label. These are indices into the vertices of a surface mesh to which this label belongs. | |
| std::vector< float > | coord_x |
| x coordinates of the vertices in case of a surface label, or voxels coordinates for a volume label. | |
| std::vector< float > | coord_y |
| y coordinates of the vertices in case of a surface label, or voxels coordinates for a volume label. | |
| std::vector< float > | coord_z |
| z coordinates of the vertices in case of a surface label, or voxels coordinates for a volume label. | |
| std::vector< float > | value |
| the value of the label, can represent continuous data like a p-value, or sometimes simply 1.0 or 0.0 (interpreted as int/bool) to mark vertices inside/outside of a certain area. | |
Detailed Description
Models a FreeSurfer label. Can be a surface or volume label. A label contains entries for a subset of the vertices of a mesh (or the voxels of a volume). For a surface label, the 'vertex' field contains a vertex index, the coord_* fields may contain the vertex coordinates, and the value field may contain some per-vertex descriptor or analysis result, like a p-value. For a volume label, the 'vertex' field contains a running number, the coord_* fields contain (as floats) the voxel R,A,S indices, and the value field may contain some per-voxel descriptor or analysis result, like a p-value. Note: The variable names herre assume this is a surface label, do not let that confuse you when working with volume labels.
