Detailed Description

template<typename Tb>
class ev::Mat::Ternary_< Tb >

Spatial map encoding event polarity at each pixel.

Positive-polarity events set the pixel to POSITIVE; negative-polarity events set it to NEGATIVE. Pixels with no events remain at ZERO. Only the last inserted polarity per pixel is retained.

The following alias is defined for convenience:

using Ternary = Ternary_<char>;

Member Function Documentation

emplace()

template<typename Tb>

template<typename T>

Tb ev::Mat::Ternary_< Tb >::emplace ( const T x, const T y, const bool p )

inline

Write polarity p at (x, y) without constructing an Event_.

Parameters

x	Spatial coordinate x
y	Spatial coordinate y
p	Polarity (true → POSITIVE, false → NEGATIVE)

Returns

New pixel value

insert()

template<typename Tb>

template<typename T>

Tb ev::Mat::Ternary_< Tb >::insert ( const Event_< T > & e )

inline

Insert an event, writing POSITIVE or NEGATIVE at (e.x, e.y) based on e.p.

Parameters

e	Event to insert

Returns

New pixel value
