void computeNormalsAndCurvatures  (  Graph &  graph, 
bool  neighborhood_1ring = false 

) 
Compute normals and curvatures for all vertices in a graph.
For each vertex the function finds its 1 or 2ring neighbors and uses pcl::computePointNormal() to calculate normal and curvature. It also flips the calculated normal towards 0,0,0 viewpoint.

[in]  neighborhood_1ring  flag which controls whether 1 or 2 ring neighborhood is used. Default is 2ring, which is slower, but produces smoother normals. 
Definition at line 55 of file common.hpp.
void computeSignedCurvatures  (  Graph &  graph  ) 
Compute the type of curvature (concave/convex) for each vertex.
The type of curvature is expressed through the sign. Convex curvature is positive and concave curvature is negative. The absolute values of curvatures are not altered by this function.
TODO: add the formula.

size_t createSubgraphsFromColorMap  (  Graph &  graph, 
ColorMap  color_map,  
std::vector< boost::reference_wrapper< Graph > > &  subgraphs  
) 
Split a given graph into subgraphs based on the values in a given vertex color map.
Each created subgraph is filled with the vertices that have the same color according to the color map. Consequently, the number of created subgraphs is equal to the number of unique colors in the provided map. The subgraphs are guaranteed to be sorted in the increasing order of the color.
In order to allow creation of subgraphs, the graph type should be an instantiation of boost::subgraph template. Note that the graph is passed by nonconst reference, because subgraph creation modifies the parent graph. Also, note that the created subgraphs are output as references wrapped with boost::reference_wrapper. The reason is that the factory function for subgraph creation in BGL returns newly created subgraphs by reference.

Find connected components in a graph and create a subgraph for each of them.
Each created subgraph is filled with the vertices that belong to the corresponding connected component.

void createSubgraphsFromIndices  (  Graph &  graph, 
const std::vector< pcl::PointIndices > &  indices,  
std::vector< boost::reference_wrapper< Graph > > &  subgraphs  
) 
Create subgraphs of a given graph containing vertices from a given indices vector.
For each set of indices in the indices
vector this function will create a subgraph containing corresponding vertices of the parent graph. An additional subgraph containing all the remaining vertices (not included in any other subgraph) will be created as well.

Retrieve the indices of the points of the point cloud stored in a point cloud (sub)graph that actually belong to the (sub)graph.
A child subgraph contains only a subset of the vertices of the parent graph. This function provides a vector of indices of the vertices of the parent graph that belong to this subgraph as well. These vertex indices are valid point indices for the point cloud stored in the parent graph.

inline 
Retrieve the indices of the points of the point cloud stored in a point cloud graph that actually belong to the graph.
Since point_cloud_graph always contain all the points that it stores, this function always returns a vector with indices from 0
to N1
, where N
is the number of vertices (points) in the graph.

inline 
Retrieve the point cloud stored in a point cloud (sub)graph.
The behavior of this function will be different for root and child subgraphs. A root subgraph will return the point cloud stored in it, whereas a child subgraph will return the point cloud stored in its parent graph.
