OpenLvVision_OpenCv.lvlib:TransformTo2D.vim

Performs a matrix transformation on the input points to project them into 2D coordinates

The function transform performs the matrix transformation of every element of the array src and stores the results in dst:

  • When m.cols == src.channels():
    $ \texttt{dst}(I) = \texttt{m} \cdot \texttt{src}(I) $
  • When m.cols == src.channels() + 1 (using an extra dimension for translation):
    $ \texttt{dst}(I) = \texttt{m} \cdot [\texttt{src}(I); 1] $

Every element of the $N$-channel array src is interpreted as an $N$-element vector that is transformed using the $M \times N$ or $M \times (N+1)$ matrix m to an $M$-element vector — the corresponding element of the output array dst.
