OpenLvVision_OpenCv.lvlib:AbsDiff.vim

Calculates the per-element absolute difference between two arrays or between an array and a scalar.

The function absdiff calculates:

  • Absolute difference between two arrays (when they have the same size and type):
    $ \texttt{dst}(I) = \texttt{saturate} (| \texttt{src1}(I) - \texttt{src2}(I)|) $
  • Absolute difference between an array and a scalar (when the second array is constructed from Scalar or has as many elements as the number of channels in src1):
    $ \texttt{dst}(I) = \texttt{saturate} (| \texttt{src1}(I) - \texttt{src2} |) $
  • Absolute difference between a scalar and an array (when the first array is constructed from Scalar or has as many elements as the number of channels in src2):
    $ \texttt{dst}(I) = \texttt{saturate} (| \texttt{src1} - \texttt{src2}(I) |) $

Where I is a multi-dimensional index of array elements. In case of multi-channel arrays, each channel is processed independently.
