cvDistTransform Method (src, dst, distanceType, maskSize, userMask, labels)

www.emgu.com/wiki

Calculates distance to closest zero pixel for all non-zero pixels of source image

Declaration Syntax

Visual Basic

Visual C++

public static void cvDistTransform(
	IntPtr src,
	IntPtr dst,
	DIST_TYPE distanceType,
	int maskSize,
	float[] userMask,
	IntPtr labels
)

Public Shared Sub cvDistTransform ( _
	src As IntPtr, _
	dst As IntPtr, _
	distanceType As DIST_TYPE, _
	maskSize As Integer, _
	userMask As Single(), _
	labels As IntPtr _
)

public:
static void cvDistTransform(
	IntPtr src, 
	IntPtr dst, 
	DIST_TYPE distanceType, 
	int maskSize, 
	array<float>^ userMask, 
	IntPtr labels
)

Parameters

src (IntPtr): Source 8-bit single-channel (binary) image.

dst (IntPtr): Output image with calculated distances (32-bit floating-point, single-channel).

distanceType (DIST_TYPE): Type of distance

maskSize (Int32): Size of distance transform mask; can be 3 or 5. In case of CV_DIST_L1 or CV_DIST_C the parameter is forced to 3, because 3x3 mask gives the same result as 5x5 yet it is faster.

userMask (array< Single >[]()[]): User-defined mask in case of user-defined distance. It consists of 2 numbers (horizontal/vertical shift cost, diagonal shift cost) in case of 3x3 mask and 3 numbers (horizontal/vertical shift cost, diagonal shift cost, knights move cost) in case of 5x5 mask.

labels (IntPtr): The optional output 2d array of labels of integer type and the same size as src and dst.
