F_VN_DistanceTransformationExp
Calculates the distance transformation, which is the distance to the closest zero pixel in a binary image. Additionally, an image with component labels is created (discrete Voronoi diagram). (expert function)

Description |
|---|---|---|
|
ipSrcImage |
Source image (USINT, 1 channel) | |
|

Reference To ITcVnImage |
Destination image (REAL, 1 channel. An appropriate destination image will be created if required.) |
|
eDistanceType |
Distance computation method (supported: L1, L2, C) | |
|
eMaskSize |
Size of the distance transformation mask (PRECISE not supported for label computation) | |

Reference To ITcVnImage |
Returns the component labels (Discrete Voronoi diagram; DINT, 1 channel. An appropriate image will be created if required.) |
|
eLabelType |
Type of the labels | |
|
hrPrev |
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) |
