  \section hotspotCalculationTestCases Testcases
 
  To see the different Hotspot-Testcases have a look at the \ref hotspottestdoc.
 
  Note from an intensive session of checking the test results:
   - itk::MultiGaussianImageSource needs a review
   - the test idea is ok, but the combination of XML files for parameters and MultiGaussianImageSource has serious flaws
     - the XML file should contain exactly the parameters that MultiGaussianImageSource requires
     - in contrast, now the XML file mentions index coordinates for gaussian centers while the MultiGaussianImageSource expects world coordinates
       - this requires a transformation (index * spacing assuming no rotation) that was actually broken until recently

-  * \brief Class for calculating statistics and histogram for an (optionally
-  * masked) image.
-  *
-  * Images can be masked by either a label image (of the same dimensions as
-  * the original image) or by a closed mitk::PlanarFigure, e.g. a circle or
-  * polygon. When masking with a planar figure, the slice corresponding to the
-  * plane containing the figure is extracted and then clipped with contour
-  * defined by the figure. Planar figures need to be aligned along the main axes
-  * of the image (axial, sagittal, coronal). Planar figures on arbitrary
-  * rotated planes are not supported.
-  *
-  * For each operating mode (no masking, masking by image, masking by planar
-  * figure), the calculated statistics and histogram are cached so that, when
-  * switching back and forth between operation modes without modifying mask or
-  * image, the information doesn't need to be recalculated.
-  *
-  * The class also has the possibility to calculate the location and separate
-  * statistics for a region called "hotspot". The hotspot is a sphere of
-  * user-defined size and its location is chosen in a way that the average
-  * pixel value within the sphere is maximized.
-  *
-  * \warning Hotspot calculation does not work in case of 2D-images!
-  *
-  * Note: currently time-resolved and multi-channel pictures are not properly
-  * supported.
-  *
-  * \section HotspotStatistics_caption Calculation of hotspot statistics
-  *
-  * Since calculation of hotspot location and statistics is not
-  * straight-forward, the following paragraphs will describe it in more detail.
-  *
-  * <b>Note: Calculation of hotspot statistics is optional and set to off by default.
-  * Multilabel-masks are supported.</b>
-  *
-  * \subsection HotspotStatistics_description Hotspot Definition
-  *
-  * The hotspot of an image is motivated from PET readings. It is defined
-  * as a spherical region of fixed size which maximizes the average pixel value
-  * within the region.  The following image illustrates the concept: the
-  * colored areas are different image intensities and the hotspot is located
-  * in the hottest region of the image.
-  *
-  * <b> Note:</b> Only hotspots are calculated for which the whole hotspot-sphere is
-  *     inside the image by default. This behaviour can be changed by
-  *     by calling SetHotspotMustBeCompletlyInsideImage().
-  * \warning Note that SetHotspotMustBeCompletlyInsideImage(false) may overrate
-  *          "hot" regions at image borders, because they have a stronger influence on the
-  *          mean value! Think clearly about this fact and make sure this is what you
-  *          want/need in your application, before calling
-  *          SetHotspotMustBeCompletlyInsideImage(false)!
-  *
-  *
-  * \image html hotspotexample.JPG
-  *
-  * \subsection HotspotStatistics_calculation Hotspot Calculation
-  *
-  * Since only the size of the hotspot is known initially, we need to calculate
-  * two aspects (both implemented in CalculateHotspotStatistics() ):
-  * - the hotspot location
-  * - statistics of the pixels within the hotspot.
-  *
-  * Finding the hotspot location requires to calculate the average value at each
-  * position. This is done by convolution of the image with a sperical kernel
-  * image which reflects partial volumes (important in the case of low-resolution
-  * PET images).
-  *
-  * Once the hotspot location is known, calculating the actual statistics is a
-  * simple task which is implemented in CalculateHotspotStatistics() using a second
-  * instance of the ImageStatisticsCalculator.
-  *
-  * <b>Step 1: Finding the hotspot by image convolution</b>
-  *
-  * As described above, we use image convolution with a rasterized sphere to
-  * average the image at each position. To handle coarse resolutions, which would
-  * normally force us to decide for partially contained voxels whether to count
-  * them or not, we supersample the kernel image and use non-integer kernel values
-  * (see GenerateHotspotSearchConvolutionKernel()), which reflect the volume part that is contained in the
-  * sphere. For example, if three subvoxels are inside the sphere, the corresponding
-  * kernel voxel gets a value of 0.75 (3 out of 4 subvoxels, see 2D example below).
-  *
-  * \image html convolutionkernelsupersampling.jpg
-  *
-  * Convolution itself is done by means of the itkFFTConvolutionImageFilter.
-  * To find the hotspot location, we simply iterate the averaged image and find a
-  * maximum location (see CalculateExtremaWorld()). In case of images with multiple
-  * maxima the method returns value and corresponding index of the extrema that is
-  * found by the iterator first.
-  *
-  * <b>Step 2: Computation of hotspot statistics</b>
-  *
-  * Once the hotspot location is found, statistics for the region are calculated
-  * by simply iterating the input image and regarding all pixel centers inside the
-  * hotspot-sphere for statistics.
-  * \warning Index positions of maximum/minimum are not provided, because they are not necessarily unique
-  * \todo If index positions of maximum/minimum are required, output needs to be changed to multiple positions / regions, etc.
-  *
-  * \subsection HotspotStatistics_tests Tests
-  *
-  * To check the correctness of the hotspot calculation, a special class
-  * (\ref hotspottestdoc) has been created, which generates images with
-  * known hotspot location and statistics. A number of unit tests use this class
-  * to first generate an image of known properites and then verify that
-  * ImageStatisticsCalculator is able to reproduce the known statistics.

   - v1 = (start;end)
   - v2 = (start;currentPoint) -> for each point of the current line segment!
 
   3. Calculate the distance from the currentPoint to v1:
 
   a. Determine the length of the orthogonal projection of v2 to v1 by:
 
   l = v2 * (normalized v1)
 
   b. There a three possibilities for the distance then:
 
   d = sqrt(lenght(v2)^2 - l^2) if l > 0 and l < length(v1)
   d = lenght(v2-v1) if l > 0 and l > lenght(v1)
   d = length(v2) if l < 0 because v2 is then pointing in a different direction than v1
 
   4. Memorize the point with the biggest distance and create two new line segments with it at the end of the iteration
   and put it into the stack
 
   5. If the distance value D <= m_Tolerance, then add the start and end index and the corresponding points to the
   reduced ones
