Member Function Documentation

compute()

void compute ( )

overridevirtual

Execute the algorithm.

Implements Algorithm.

takeOutput()

OwningDataList takeOutput ( )

overridevirtual

Return any new Data that was created by the Algorithm during the last call to compute().

The default implementation will return an empty list.

Note

Since ownership of the data is transferred, you can call this method only once between calls to compute().

Reimplemented from Algorithm.

skeletonAsRawGraph()

static std::optional< detail::GraphImpl< int > > skeletonAsRawGraph ( const SharedImage & skeleton, bool simplify = true )

staticprotected

Convert a skeleton image to a raw graph structure.

The nodes of the graph are the (integer) pixel indices, and the edges are the l^1 distances between the nodes. If simplify is set to true, then we remove edges that are part of small cycles.

rawSkeletonGraphToGraph()

static std::unique_ptr< Graph > rawSkeletonGraphToGraph ( const detail::GraphImpl< int > & graph, ImageDescriptorWorld desc, SharedImage * potential = nullptr )

staticprotected

Convert a graph as returned by skeletonAsGraph into a Graph.

Nodes are coordinates of pixels, edges initially have a single point being the midpoint between the nodes. If combineChains is true, chains like n0 - n1 - n2, where n1 has no other edges, are combined to longer edges n0 – n2 The parameter smoothing controls the smoothing strength (0 means no smoothing).
