FIL.CreateSegmentFittingMap

Precomputes a data object that is required for fast segment fitting on images.

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

C++
C#
 
public static void CreateSegmentFittingMap
(
	FilNet.ImageFormat inImageFormat,
	FilNet.SegmentFittingField inFittingField,
	FilNet.CoordinateSystem2D? inFittingFieldAlignment,
	int inScanCount,
	int inScanWidth,
	FilNet.SamplingParams inSamplingParams,
	FilNet.SegmentFittingMap outFittingMap,
	IList<FilNet.Segment2D> diagScanSegments,
	IList<FilNet.Rectangle2D> diagSamplingAreas
)

Parameters

Name Type Range Default Description
inImageFormatFilNet.ImageFormatDimensions, depth and pixel type of the images on which fitting will be performed.
inFittingFieldFilNet.SegmentFittingFieldDefines a rectangle in which scan segments will be created.
inFittingFieldAlignmentFilNet.CoordinateSystem2D?Adjusts the fitting field to the position of the inspected object. Default value: ftl::NIL.
inScanCountint<3, INF>10The number of points that will be searched to estimate the position of the segment. Default value: 10.
inScanWidthint<1, INF>5The width of each scan field (in pixels). Default value: 5.
inSamplingParamsFilNet.SamplingParams.interpolation BilinearParameters controlling the sampling process. Default value: .interpolation Bilinear.
outFittingMapFilNet.SegmentFittingMapOptimized data required for segment fitting.
diagScanSegmentsSystem.Collections.Generic.IList<FilNet.Segment2D>Segments along which the scans will be run.
diagSamplingAreasSystem.Collections.Generic.IList<FilNet.Rectangle2D>Scan fields created for point detection.

Description

The operation creates a series of scan maps that can be later used by other Shape Fitting filters. Each scan map corresponds to a single scan segment of inScanWidth length.

The optional parameter inFittingFieldAlignment defines the transform to be performed on the inFittingField so that the result is defined in a new context, e.g. returned by one of Template Matching filters.
