Detailed Description

template<typename T>
class ev::Event_< T >

This class extends cv::Point_<T> for event data. For more information, please refer here.

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

using Eventi = Event_<int>;
using Eventl = Event_<long>;
using Eventf = Event_<float>;
using Eventd = Event_<double>;
using Event = Eventi;

Examples

example-event-histogram.cpp, example-event-image.cpp, example-event.cpp, example-plain-text-reader.cpp, example-point-cloud.cpp, and example-time-surface.cpp.
