Parameters

Name Type Range Default Description
inImageAvl.ImageInput image.
inPathsSystem.Collections.Generic.List<Avl.Path>Paths to be adjusted. For sparse, synthetic paths the inPointSpacing needs to be specified.
inPointSpacingAtl.Optional<float><1.0f, INF>If set, sampling points of the input path will be equidistant with specified spacing. Useful for increasing density of synthetic, sparse paths. Default value: atl::NIL.
inAlignmentAtl.Optional<Avl.CoordinateSystem2D>Alignment to be corrected, usually connects to outObject.Alignment of LocateObjects filter. Default value: atl::NIL.
inAttractionRadiusfloat<0.1f, INF>2.0fExpected initial distance between inPaths and edges of the input image. Default value: 2.0f.
inAdjustmentMetricAvl.AdjustmentMetricSegmentDistanceMetric used for path attraction. The SegmentDistance minimizes distances along path normal vectors, and thus adjustment is more accurate. PointDistance_* minimize euclidean distance, adjustment tends to be more stable. Default value: SegmentDistance.
inAdjustTranslationboolTrueCompute the translation part of adjustment transform. Must be true when using AttractPathTangents estimation method. Default value: True.
inAdjustRotationboolTrueCompute the rotation part of adjustment transform. Default value: True.
inAdjustScaleboolFalseCompute the scale part of adjustment transform. Default value: False.
inIterationCountint<0, 100>6Number of iterations of internal adjustment algorithm. Default value: 6.
inBaseGradientfloat<0.1f, INF>1.0fThreshold for suppression of weak input image gradients. Increase for very noisy images. Default value: 1.0f.
outAdjustedPathsSystem.Collections.Generic.List<Avl.Path>Adjusted output paths.
outAlignmentAvl.CoordinateSystem2DCorrected alignment - the inAlignment input modified with estimated adjustment parameters.
diagAttractionVectorsAvl.Diagnostic<System.Collections.Generic.List<Avl.Segment2D>>Attraction vectors from first iteration.
