Class ViewNeighbors

java.lang.Object

net.preibisch.mvrecon.process.interestpointregistration.ViewNeighbors

public class ViewNeighbors
extends Object

Reusable per-view neighbour queries:

• connectedViews(SpimData2, Collection, Map) — interest-point correspondence neighbours
• overlappingViews(SpimData2, Collection) — geometric (bounding-box) neighbours

Both restrict their results to the universe set passed in (typically the views the caller is already analysing). "Connected" follows the same same-label / canonical-pair semantics as AnalyzeErrorsUtil.getErrors but skips transforms and distance — it's just the connection graph.

Method Details

connectedViews

public static Map<mpicbg.spim.data.sequence.ViewId,Set<mpicbg.spim.data.sequence.ViewId>> connectedViews(SpimData2 data,
 Collection<? extends mpicbg.spim.data.sequence.ViewId> universe,
 Map<String,Double> labelAndWeights)

For each view in universe, return the set of other views in universe that share at least one same-label correspondence with it. Symmetric.

connectedTo

public static Set<mpicbg.spim.data.sequence.ViewId> connectedTo(mpicbg.spim.data.sequence.ViewId v,
 SpimData2 data,
 Collection<? extends mpicbg.spim.data.sequence.ViewId> universe,
 Map<String,Double> labelAndWeights)

Convenience: connected set for a single view (returns empty set if v not in universe).

connectedFor

public static Set<mpicbg.spim.data.sequence.ViewId> connectedFor(SpimData2 data,
 Collection<? extends mpicbg.spim.data.sequence.ViewId> actual,
 Collection<? extends mpicbg.spim.data.sequence.ViewId> universe,
 Map<String,Double> labelAndWeights)

Per-click connectivity query. Returns the views in universe \ actual that share at least one same-label correspondence with any view in actual. Walks only the actual set's correspondence lists — much cheaper than connectedViews(SpimData2, Collection, Map) which materialises the full universe-by-universe graph. Weight values in labelAndWeights are ignored (connectedness is binary); only the key set matters.

overlappingViews

public static Map<mpicbg.spim.data.sequence.ViewId,Set<mpicbg.spim.data.sequence.ViewId>> overlappingViews(SpimData2 data,
 Collection<? extends mpicbg.spim.data.sequence.ViewId> universe)

For each view in universe, return the set of other views in universe whose registered bounding-box overlaps it. Symmetric.

overlappingWith

public static Set<mpicbg.spim.data.sequence.ViewId> overlappingWith(mpicbg.spim.data.sequence.ViewId v,
 SpimData2 data,
 Collection<? extends mpicbg.spim.data.sequence.ViewId> universe)

Convenience: overlap set for a single view.

overlappingFor

public static Set<mpicbg.spim.data.sequence.ViewId> overlappingFor(SpimData2 data,
 Collection<? extends mpicbg.spim.data.sequence.ViewId> actual,
 Collection<? extends mpicbg.spim.data.sequence.ViewId> universe)

Per-click overlap query. Returns the views in universe \ actual whose affine-transformed body intersects any view in actual. Two-stage pipeline:

1. AABB broad phase — one union AABB over actual, then a parallel scan over universe reusing SimpleBoundingBoxOverlap.overlaps(V, V) to prune.
2. SAT narrow phase — for each AABB-positive candidate, check 3-D SAT against each view in actual; first hit wins.

Avoids the O(N²) full-graph precompute that overlappingViews(SpimData2, Collection) performs. Suitable for interactive use over universes with hundreds of thousands of views.
