.. java:type:: public class FindLocalMaxima

   Find local maxima in an Image (or ROI) using the algorithm described in Neubeck and Van Gool. Efficient non-maximum suppression. Pattern Recognition (2006) vol. 3 pp. 850-855 Jonas Ries brought this to my attention and send me C code implementing one of the described algorithms

Methods
-------
FindMax
^^^^^^^

.. java:method:: public static Polygon FindMax(ImageProcessor iProc, Roi roi, int n, int threshold, FilterType filterType)
   :outertype: FindLocalMaxima

   Static utility function to find local maxima in an Image

   :param iProc: - ImageProcessor object in which to look for local maxima
   :param roi: - region of interest to which the analysis is constrained
   :param n: - minimum distance to other local maximum
   :param threshold: - value below which a maximum will be rejected
   :param filterType: - Prefilter the image. Either none or Gaussian1_5
   :return: Polygon with maxima

noiseFilter
^^^^^^^^^^^

.. java:method:: public static Polygon noiseFilter(ImageProcessor iProc, Polygon inputPoints, int threshold)
   :outertype: FindLocalMaxima

   :param iProc:
   :param inputPoints:
   :param threshold:
