DistanceTransform


Header: FIL.h
Namespace: fil
Module: FoundationBasic

Computes an image in which the pixel values denote the estimated distances to the nearest bright pixel in the input image.

Applications: This is an initial step of some advanced traditional image analysis algorithms.

Syntax

C++
C#
 
void fil::DistanceTransform
(
	const fil::Image& inImage,
	int inThreshold,
	float inStraightDistance,
	float inDiagonalDistance,
	float inMaxDistance,
	fil::Image& outImage
)
