OpenLvVision_OpenCv.lvlib:InRange.vim

Checks if array elements lie between the elements of two other arrays.

The function checks the range as follows:

  • For every element of a single-channel input array:
    $ \texttt{dst}(I) = \texttt{lowerb}(I)_0 \leq \texttt{src}(I)_0 \leq \texttt{upperb}(I)_0 $
  • For two-channel arrays:
    $ \texttt{dst}(I) = \texttt{lowerb}(I)_0 \leq \texttt{src}(I)_0 \leq \texttt{upperb}(I)_0 \land \texttt{lowerb}(I)_1 \leq \texttt{src}(I)_1 \leq \texttt{upperb}(I)_1 $
  • And so forth.

That is, dst(I) is set to 255 (all 1-bits) if src(I) is within the specified 1D, 2D, 3D, ... box, and 0 otherwise.

When the lower and/or upper boundary parameters are scalars, the indices (I) at lowerb and upperb in the above formulas should be omitted.
