public static void AdjustPathArrayToEdges ( AvlNet.Image inImage, IList<AvlNet.Path> inPaths, float? inPointSpacing, AvlNet.CoordinateSystem2D? inAlignment, float inAttractionRadius, AvlNet.AdjustmentMetric inAdjustmentMetric, bool inAdjustTranslation, bool inAdjustRotation, bool inAdjustScale, int inIterationCount, float inBaseGradient, IList<AvlNet.Path> outAdjustedPaths, out AvlNet.CoordinateSystem2D outAlignment, IList<AvlNet.Segment2D> diagAttractionVectors )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | AvlNet.Image | Input image. | |||
inPaths | System.Collections.Generic.IList<AvlNet.Path> | Paths to be adjusted. For sparse, synthetic paths the inPointSpacing needs to be specified. | |||
inPointSpacing | 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. | ||
inAlignment | AvlNet.CoordinateSystem2D? | Alignment to be corrected, usually connects to outObject.Alignment of LocateObjects filter. Default value: atl::NIL. | |||
inAttractionRadius | float | <0.1f, INF> | 2.0f | Expected initial distance between inPaths and edges of the input image. Default value: 2.0f. | |
inAdjustmentMetric | AvlNet.AdjustmentMetric | SegmentDistance | Metric 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. | ||
inAdjustTranslation | bool | True | Compute the translation part of adjustment transform. Must be true when using AttractPathTangents estimation method. Default value: True. | ||
inAdjustRotation | bool | True | Compute the rotation part of adjustment transform. Default value: True. | ||
inAdjustScale | bool | False | Compute the scale part of adjustment transform. Default value: False. | ||
inIterationCount | int | <0, 100> | 6 | Number of iterations of internal adjustment algorithm. Default value: 6. | |
inBaseGradient | float | <0.1f, INF> | 1.0f | Threshold for suppression of weak input image gradients. Increase for very noisy images. Default value: 1.0f. | |
outAdjustedPaths | System.Collections.Generic.IList<AvlNet.Path> | Adjusted output paths. | |||
outAlignment | AvlNet.CoordinateSystem2D | Corrected alignment - the inAlignment input modified with estimated adjustment parameters. | |||
diagAttractionVectors | System.Collections.Generic.IList<AvlNet.Segment2D> | Attraction vectors from first iteration. |
