You are here: Start » AVL.NET » Invoke.ExtendSegment

Extends a segment at both endpoints by walking 1 pixel at a time along the segment direction, stopping when the in-place Sobel gradient magnitude at the next position drops below threshold or the image boundary is reached.

Syntax

public static void ExtendSegment
(
	Avl.Image inImage,
	Avl.Segment2D inSegment,
	float inEdgeThreshold,
	Avl.InterpolationMethod inInterpolation,
	out Avl.Segment2D outSegment
)

Parameters

	Name	Type	Range	Default	Description
	inImage	Avl.Image			Input image (gradient is computed in-place).
	inSegment	Avl.Segment2D			Segment to extend.
	inEdgeThreshold	float	<0.0f, INF>	10.0f	Minimum Sobel gradient magnitude required to continue extending. Default value: 10.0f.
	inInterpolation	Avl.InterpolationMethod		Bilinear	NearestNeighbour snaps the walking position to the integer grid; Bilinear samples all Sobel neighbours at real-valued coordinates. Default value: Bilinear.
	outSegment	Avl.Segment2D			Extended segment.
