Math and std::vector code snippet to calculate a cumulative histogram from a histogram.


//From htpp://www.richelbilderbeek.nl/CppGetCumulativeHistogram.htm

template <class T> const std::vector<T> GetCumulativeHistogram(const std::vector<T>& histogram)

{

  std::vector<T> v(histogram.begin(),histogram.end() );

  const int size = static_cast<int>(v.size());

  for (int i=1; i!=size; ++i)

  {

    v[i] += v[i-1];

  }

  return v;

}
