OpenLvVision_OpenCv.lvlib:Scharr.vim

Calculates the first x- or y- image derivative using Scharr operator.

The function computes the first $x$- or $y$- spatial image derivative using the Scharr operator. The call:

$ \texttt{Scharr(src, dst, ddepth, dx, dy, scale, delta, borderType)} $

is equivalent to:

$ \texttt{Sobel(src, dst, ddepth, dx, dy, FILTER\_SCHARR, scale, delta, borderType)} $

The Scharr operator is typically more accurate than the Sobel operator for calculating gradients, especially for $3 \times 3$ kernels.

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.

BORDER_REFLECT_101 = 4, `gfedcb|abcdefgh|gfedcba`

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