OpenLvVision_OpenCv.lvlib:Dilate.vim

Dilates an image by using a specific structuring element.

The function dilates the source image using the specified structuring element that determines the shape of a pixel neighborhood over which the maximum is taken:

$ \texttt{dst}(x,y) = \max_{(x',y'): \, \texttt{element}(x',y') \neq 0} \texttt{src}(x+x',y+y') $

The function supports the in-place mode. Dilation can be applied several (iterations) times. In case of multi-channel images, each channel is processed independently.

For detailed information, please refer to the OpenCV documentation

error in

error in can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.

Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

    cbool

    		status

    status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

    Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

    cstr

    		source

    source describes the origin of the error or warning.

cOpenLvVision__OpenCv_lvlib_Anythinglvclass

Src

input image; the number of channels can be arbitrary, but the depth should be one of CV_8U, CV_16U, CV_16S, CV_32F or CV_64F.

cOpenLvVision__OpenCv_lvlib_Anythinglvclass

Dst

output image of the same size and type as src.

cnclst

Anchor

position of the anchor within the element; default value (-1, -1) means that the anchor is at the element center.

iterations

number of times dilation is applied.

BorderTypes

pixel extrapolation method, see BorderTypes. BORDER_WRAP is not suported.

BORDER_CONSTANT = 0, !< `iiiiii|abcdefgh|iiiiiii` with some specified `i`

BORDER_REPLICATE = 1, `aaaaaa|abcdefgh|hhhhhhh`

BORDER_REFLECT = 2, `fedcba|abcdefgh|hgfedcb`

BORDER_WRAP = 3, `cdefgh|abcdefgh|abcdefg`

BORDER_REFLECT_101 = 4, `gfedcb|abcdefgh|gfedcba`

BORDER_TRANSPARENT = 5, `uvwxyz|abcdefgh|ijklmno` - Treats outliers as transparent.

BORDER_ISOLATED = 16 Interpolation restricted within the ROI boundaries.

borderValue

border value in case of a constant border

Kernel

structuring element used for dilation; if element=Mat(), a 3 x 3 rectangular structuring element is used. Kernel can be created using getStructuringElement
