Method Detail

• computeCrossCorrelationMT

  public double[] computeCrossCorrelationMT(double relMinOverlapX,
                                            double relMinOverlapY,
                                            boolean showImages)

  Computes a translational registration with the help of the cross correlation measure.
  Limits the overlap to 30% and restricts the shift furthermore by a factor you can tell him (this is useful if you f. ex. know that the vertical shift is much less than the horizontal). NOTE: Works multithreaded

  Parameters:

  relMinOverlapX - double - if you want to scan for less possible translations seen from a direct overlay, give the relative factor here (e.g. 0.3 means DONOT scan the outer 30%) NOTE: Below 0.05 does not really make sense as you then compare only very few pixels (even one) on the edges which gives then an R of 1 (perfect match)

  relMinOverlapY - double - if you want to scan for less possible translations seen from a direct overlay, give the relative factor here (e.g. 0.3 means DONOT scan the outer 30%) NOTE: Below 0.05 does not really make sense as you then compare only very few pixels (even one) on the edges which gives then an R of 1 (perfect match)

  showImages - boolean - Show the result of the cross correlation translation

  Returns:

  double[] return a double array containing {displaceX, displaceY, R}
