Parameters

src

Type: OpenCvSharpCvArr
Source 8-bit single-channel (binary) image.

dst

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

distanceType

Type: OpenCvSharpDistanceType
Type of distance.

maskSize

Type: SystemInt32
Size of distance transform mask; can be 3, 5 or 0. In case of CV_DIST_L1 or CV_DIST_C the parameter is forced to 3, because 3×3 mask gives the same result as 5x5 yet it is faster. When mask_size==0, a different non-approximate algorithm is used to calculate distances.

mask

Type: SystemSingle
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, knight’s move cost) in case of 5x5 mask.

labels

Type: OpenCvSharpCvArr
The optional output 2d array of labels of integer type and the same size as src and dst, can now be used only with mask_size==3 or 5.
