Synopses

Declared in <boost/gil/image_processing/histogram_equalization.hpp>

Overload for histogram equalization algorithm, takes in a single source histogram and returns the color map used for histogram equalization.

Overload for histogram equalization algorithm, takes in both source histogram & destination histogram and returns the color map used for histogram equalization as well as transforming the destination histogram.

template<
    typename SrcKeyType,
    typename DstKeyType>
std::map<SrcKeyType, DstKeyType>
histogram_equalization(
    histogram<SrcKeyType> const& src_hist,
    histogram<DstKeyType>& dst_hist);

    typename DstView>
void
histogram_equalization(
    SrcView const& src_view,
    DstView const& dst_view,
    std::size_t bin_width = 1,
    bool mask = false,
    std::vector<std::vector<bool>> src_mask = {});
