AVL.CreatePathFittingMap

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

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax

C++
C#
 
public static void CreatePathFittingMap
(
	AvlNet.ImageFormat inImageFormat,
	AvlNet.PathFittingField inFittingField,
	AvlNet.CoordinateSystem2D? inFittingFieldAlignment,
	float? inScanStep,
	int inScanWidth,
	AvlNet.SamplingParams inSamplingParams,
	AvlNet.PathFittingMap outFittingMap,
	IList<AvlNet.Segment2D> diagScanSegments,
	IList<AvlNet.Rectangle2D> diagSamplingAreas
)

Parameters

Name Type Range Default Description
inImageFormatAvlNet.ImageFormatDimensions, depth and pixel type of the images on which fitting will be performed.
inFittingFieldAvlNet.PathFittingFieldDefines a stripe in which scan segments will be created.
inFittingFieldAlignmentAvlNet.CoordinateSystem2D?Adjusts the fitting field to the position of the inspected object. Default value: atl::NIL.
inScanStepfloat?<0.0f, INF>Optional implicit conversion of the input path to an equidistant one. Default value: atl::NIL.
inScanWidthint<1, INF>5The width of each scan field (in pixels). Default value: 5.
inSamplingParamsAvlNet.SamplingParams.interpolation BilinearParameters controlling the sampling process. Default value: .interpolation Bilinear.
outFittingMapAvlNet.PathFittingMapOptimized data required for path fitting.
diagScanSegmentsSystem.Collections.Generic.IList<AvlNet.Segment2D>Segments along which the scans will be run.
diagSamplingAreasSystem.Collections.Generic.IList<AvlNet.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.
