Detailed Description

Spatial map accumulating signed event counts per pixel.

Each positive-polarity event increments the pixel counter by +1; each negative-polarity event decrements it by -1. Counters are stored as CounterType (int16_t by default).

Member Function Documentation

emplace()

template<typename T>

CounterType ev::Mat::Counter::emplace ( const T x, const T y, const bool p )

inline

Increment or decrement the counter at (x, y) without constructing an Event_.

Parameters

x	Spatial coordinate x
y	Spatial coordinate y
p	true to increment (+1), false to decrement (-1)

Returns

Updated counter value

insert()

template<typename T>

CounterType ev::Mat::Counter::insert ( const Event_< T > & e )

inline

Insert an event, incrementing (p=true) or decrementing (p=false) the counter at (e.x, e.y).

Parameters

e	Event to insert

Returns

Updated counter value
