Detailed Description

template<typename T, const RepresentationOptions Options = RepresentationOptions::NONE>
class ev::EventHistogram_< T, Options >

This class extends ev::EventImage_<T> for event 2D histograms.

Analogously to OpenCV library, the following aliases are defined for convenience:

using EventHistogram1b = EventHistogram_<uchar>;
using EventHistogram2b = EventHistogram_<cv::Vec2b>;
using EventHistogram3b = EventHistogram_<cv::Vec3b>;
using EventHistogram4b = EventHistogram_<cv::Vec4b>;
using EventHistogram1s = EventHistogram_<short>;
using EventHistogram2s = EventHistogram_<cv::Vec2s>;
using EventHistogram3s = EventHistogram_<cv::Vec3s>;
using EventHistogram4s = EventHistogram_<cv::Vec4s>;
using EventHistogram1w = EventHistogram_<ushort>;
using EventHistogram2w = EventHistogram_<cv::Vec2w>;
using EventHistogram3w = EventHistogram_<cv::Vec3w>;
using EventHistogram4w = EventHistogram_<cv::Vec4w>;
using EventHistogram1i = EventHistogram_<int>;
using EventHistogram2i = EventHistogram_<cv::Vec2i>;
using EventHistogram3i = EventHistogram_<cv::Vec3i>;
using EventHistogram4i = EventHistogram_<cv::Vec4i>;
using EventHistogram1f = EventHistogram_<float>;
using EventHistogram2f = EventHistogram_<cv::Vec2f>;
using EventHistogram3f = EventHistogram_<cv::Vec3f>;
using EventHistogram4f = EventHistogram_<cv::Vec4f>;
using EventHistogram1d = EventHistogram_<double>;
using EventHistogram2d = EventHistogram_<cv::Vec2d>;
using EventHistogram3d = EventHistogram_<cv::Vec3d>;
using EventHistogram4d = EventHistogram_<cv::Vec4d>;
using EventHistogram1 = EventHistogram1b;
using EventHistogram3 = EventHistogram3b;
using EventHistogram = EventHistogram1;
