Detailed Description

Public topology-only computation of node distance fields and profiles.

Exact single-node fields use a directed provider that transforms only the requested support bounding box after shared topology indexes are built. Approximate fields and both profile backends retain their hierarchy-wide traversal semantics.

computeNodeField()

static NodeDistanceField mmcfilters::DistanceTransformComputation::computeNodeField ( const MorphologicalTree &  tree, NodeId  node, DistanceTransformAccuracy  accuracy = DistanceTransformAccuracy::Exact  )

inlinestatic

Materializes the compact field of one live node.

Parameters

tree	Regular 2D morphological-tree topology.
node	Live internal node to materialize.
accuracy	Exact or approximate numerical backend.

Returns

Self-contained support pixels and aligned squared distances.

Exact accuracy transforms only the selected node. Approximate accuracy traverses the shared hierarchy-wide DIFT and copies only this node.

computeProfiles()

static DistanceTransformProfiles mmcfilters::DistanceTransformComputation::computeProfiles ( const MorphologicalTree &  tree, DistanceTransformAccuracy  accuracy = DistanceTransformAccuracy::Exact  )

inlinestatic

Computes sorted sparse histograms for every live node.

Parameters

tree	Regular 2D morphological-tree topology.
accuracy	Exact or approximate numerical backend.

Returns

Self-contained CSR-like all-node sparse profiles.

The approximate backend selects a histogram-only observer, avoiding scalar- and spatial-moment storage and updates.
