Class LabelProximityDetector

java.lang.Object

sc.fiji.snt.analysis.detection.LabelProximityDetector

public final class LabelProximityDetector
extends Object

Detects contact points between traced paths and labeled surfaces (from a segmentation/label image). For each unique label, a calibrated Euclidean Distance Transform (EDT) is computed, and path nodes within a configurable distance threshold are emitted as Detections.

Two detection modes are supported:

• Threshold mode (LabelProximityDetector.Config.distanceThreshold > 0): all nodes whose EDT distance is ≤ the threshold are detected.
• Closest-approach mode (LabelProximityDetector.Config.distanceThreshold = 0): for each path–label pair, only the node closest to the label boundary is detected.
