[Insight-users] SpatialObjects and Images

[Julien Jomier]

Hi Emiliano,

There is a class named itkSpatialObjectToImageStatisticsCalculator which 
takes an image and a spatialObject and returns the statistics of the 
image only inside the given object.

However, I don't think it's currently returning the sum of the pixels, 
but it should be easy to add. Give me some time and I'll check this into 
the cvs repository. I'll also add a function to return the number of 
pixels inside the object.
