Method Detail

• setThreshold

  void setThreshold(T threshold)

  Set the threshold value under which (or over which, in the case of a minima finder) pixels are ignored. If null, then all pixels are taken into account.

• getRegionalExtrema

  ArrayList<ArrayList<int[]>> getRegionalExtrema()

  Returns the ArrayList containing the coordinates of the local extrema found. Each element of the ArrayList is a int array, representing the coordinate of the found extrema, in the same order that of the source Image.

  Returns:

  the ArrayList containing the extrema coordinates

• getRegionalExtremaCenters

  ArrayList<float[]> getRegionalExtremaCenters()

  Computes the average coordinate of the extrema locations. This average coordinates are returned, and represents the "center" of the regional maximum. Note that this is not guaranteed to be in the regional maximum itself (imagine a regional maximum that is a ring shape; the direct center is not part of the regional maximum itself, but is what would be computed by this function). Return null if the Algorithm.process() method has not bee called.

  Returns:

  The coordinates of the "center pixel" of the regional maximum. It will always be a 3-elements float arrays, even for 2D case.

• allowEdgeExtrema

  void allowEdgeExtrema(boolean flag)

  If set to true before the Algorithm.process() method is called, then extrema found at the edges of the image bounds (including time edges) will not be pruned, and will be included in the result array.

  Parameters:

  flag -

• setOutOfBoundsStrategyFactory

  void setOutOfBoundsStrategyFactory(OutOfBoundsStrategyFactory<T> strategy)

  Set the strategy used by this extrema finder to deal with edge pixels. By default, it is an OutOfBoundsStrategyValueFactory set with the value 0 to avoid nasty edge effects.

  Parameters:

  strategy - the strategy to set
