OpenLvVision_OpenCv.lvlib:SqrBoxFilter.vim

Calculates the normalized sum of squares of the pixel values overlapping the filter.

For every pixel ( x , y ) in the source image, the function calculates the sum of squares of those neighboring pixel values which overlap the filter placed over the pixel ( x , y ).

The unnormalized square box filter can be useful in computing local image statistics such as the local variance and standard deviation around the neighborhood of a pixel.

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.

BorderTypes

border mode used to extrapolate pixels outside of the image, see BorderTypes. BORDER_WRAP is not supported.

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.
