Method DistanceTransform

Namespace

OpenCvSharp

Assembly

OpenCvSharp.dll

DistanceTransform(InputArray, OutputArray, DistanceTypes, DistanceTransformMasks, int)

computes the distance transform map

public static void DistanceTransform(InputArray src, OutputArray dst, DistanceTypes distanceType, DistanceTransformMasks maskSize, int dstType = 4)

Parameters

src InputArray

8-bit, single-channel (binary) source image.

dst OutputArray

Output image with calculated distances. It is a 8-bit or 32-bit floating-point, single-channel image of the same size as src.

distanceType DistanceTypes

Type of distance

maskSize DistanceTransformMasks

Size of the distance transform mask, see #DistanceTransformMasks. In case of the #DIST_L1 or #DIST_C distance type, the parameter is forced to 3 because a 3x3 mask gives the same result as 5x5 or any larger aperture.

dstType int

Type of output image. It can be MatType.CV_8U or MatType.CV_32F. Type CV_8U can be used only for the first variant of the function and distanceType == #DIST_L1.
