Event abstract representation.
This is an auxiliary class. This class cannot be instanced.
Definition abstract-representation.hpp:127
This class extends cv::Point_<T> for event data. For more information, please refer here.
Definition types.hpp:62
bool p
Definition types.hpp:65
double t
Definition types.hpp:64
This class is used to represent events as point clouds.
Definition point-cloud.hpp:52
void visualize(const int t, const double time_scale=1.0, const double axis_size=1.0, const double point_size=2.0)
Visualize point cloud.
bool contains(const Event_< E > &e) const
Check if an event is included in the point cloud.
