FitPathToRidges3D


Performs a series of 1D ridge detections in 3D and creates a path from the detected points.

Name Type Range Description
inSurface Surface Surface to fit the path to
inFittingField PathFittingField Path fitting field
inFittingFieldAlignment CoordinateSystem2D* Adjusts the fitting field to the position of the inspected object
inScanStep Real* 0.0 - Optional implicit conversion of the input path to an equidistant one
inSamplingStep Real* Desired distance between consecutive sampling points on the scan segments; if Nil, the bigger of surface X and Y scales is chosen
inScanWidth Integer 1 - The width of each scan field (in pixels)
inSurfaceInterpolation InterpolationMethod Interpolation method used for extraction of surface points
inRidgeScanParams RidgeScanParams3D Parameters controlling the ridge extraction process
inRidgeSelection Selection Selection mode of ridges
inLocalBlindness LocalBlindness* Defines conditions in which weaker ridges can be detected in the vicinity of stronger ridges
inMaxProfileGapWidth Integer* 0 - Maximal number of consecutive not existing profile points
inMaxPathInterpolationLength Integer* 0 - Maximal number of consecutive points not found
inMaxDeviationDelta Real* 0.0 - Maximal difference between deviations of consecutive path points
inMaxIncompleteness Real 0.0 - 0.999 Maximal fraction of ridge points not found
outPath Point3DArray? Fitted path or nothing if the fitting failed
outRidges SurfaceRidge1D?Array Found ridges
outDeviationProfile Profile? Profile of distances between the actual path points and the corresponding reference path points
outAlignedFittingField PathFittingField Fitting field used; in the image coordinate system
diagScanSegments Segment2DArray Segments along which the scans were run
diagSamplingAreas Rectangle2DArray Areas from which the input image is sampled
diagHeightProfiles ProfileArray Extracted surface height profiles
diagResponseProfiles ProfileArray Profiles of the ridge operator response
