[Insight-users] Two-dimensional histogram

[Luis Ibanez]

Hi Serg,

There are many different ways of doing this,

but

here is a suggestion that would require a rather small
amount of code writing on your part:

1) Take your input image and pass it through the
    itkMeanImageFilter.
http://www.itk.org/Insight/Doxygen/html/classitk_1_1MeanImageFilter.html

2) Take both the input, and the output of the Mean
    image filter and connect them as inputs to the
    JoinImageFilter.
http://www.itk.org/Insight/Doxygen/html/classitk_1_1JoinImageFilter.html
    The output of this filter will
    be an image of pixels with two components where
    the first component is the pixel value of the
    original input image and the second component
    is the mean value around that pixel.

3) Connect the output of the JoinImageFilter to
    the ImageToHistogramGenerator.
http://www.itk.org/Insight/Doxygen/html/classitk_1_1Statistics_1_1ImageToHistogramGenerator.html
    The output of the generator will be the 2-D
    histogram that you seem to be looking for.


BTW, You may find useful to look at the code in
Insight/Examples/Statistics/ImageHistogram3.cxx


Please let us know if you find any problems.


    Thanks


       Luis
