Method Summary

private static SkeletonBranch	createPart(SkeletonNode startnode, SkeletonNode endnode, java.util.List<SkeletonNode> nodesOnPart) If an end node or junction node has been reached, this function can be used to create the part between the startnode and the current node.
private static boolean	isVisited(boolean[][][] visited, SkeletonNode node) Check if the specified node has already been visited.
private static void	markAsVisited(boolean[][][] visited, SkeletonNode node) Mark the the specified node as visited.
static java.util.List<SkeletonBranch>	samplePartsPerStartNode(SkeletonNode startnode, int[][][] thinningcube, java.util.List<SkeletonNode> endnodes, java.util.List<SkeletonNode> junctionnodes, double widthDim, double heightDim, double depthDim) sample all skeleton parts emanating from the specified startnode which has to be a critical node, that is, either end node or junction node.

samplePartsPerStartNode

public static java.util.List<SkeletonBranch> samplePartsPerStartNode(SkeletonNode startnode,
                                                                     int[][][] thinningcube,

                                                              throws InvalidSkeletonException

sample all skeleton parts emanating from the specified startnode which has to be a critical node, that is, either end node or junction node.

Parameters:

startnode - - the node where to start sampling all parts

thinningcube - - the skeleton information, where each "not-skeleton" element has entry 0

endnodes - - a list of all end nodes in the skeleton

junctionnodes - - a list of all junction nodes in the skeleton

Throws:

InvalidSkeletonException - - if the skeleton seems to be broken

markAsVisited

private static void markAsVisited(boolean[][][] visited,
                                  SkeletonNode node)

Mark the the specified node as visited.

Parameters:

visited - - 3d array where the coordinates of the passed node are set to true

node - - the node to mark as visited

isVisited

private static boolean isVisited(boolean[][][] visited,
                                 SkeletonNode node)

Check if the specified node has already been visited.

Parameters:

visited - - 3d array where an entry is set to true if these coordinates already have been visited

node - - the node to check for if this was already visited

Returns:

true if the node's coordinates are marked as visited, false if not

createPart

private static SkeletonBranch createPart(SkeletonNode startnode,
                                         SkeletonNode endnode,
                                         java.util.List<SkeletonNode> nodesOnPart)

If an end node or junction node has been reached, this function can be used to create the part between the startnode and the current node. A copy of the list of all visited nodes is set as visited nodes in the part, and the original (temporary) list is cleared.

Parameters:

startnode - - the startnode of the new part

endnode - - the endnode of the new part

nodesOnPart - - all nodes lieing on this part, in the order of their occurance. Warning: this list cleared in the function.

Returns:

a skeleton part, starting at startnode and ending at end node, connected by the list of skeleton nodes passed as nodesOnPath
