Member Function Documentation

clear() [1/2]

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

void ev::AbstractRepresentation_< T, Options, E >::clear

(

)

Remove all events from the representation.

Note

The way in which the events are removed should be implemented in the derived classes.

clear() [2/2]

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

void ev::AbstractRepresentation_< T, Options, E >::clear

(

const cv::Mat &

background

)

Remove all events from the representation and add a background image.

Note

The way in which the events are removed should be implemented in the derived classes.

count()

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

std::size_t ev::AbstractRepresentation_< T, Options, E >::count ( ) const

inlinenodiscard

Number of events integrated in the representation.

Returns

Number of events

duration()

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

double ev::AbstractRepresentation_< T, Options, E >::duration ( ) const

inlinenodiscard

Time difference between the oldest and the newest event integrated in the representation.

Returns

Time difference. Returns -1 if time limits are not properly set.

insert() [1/4]

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

template<std::size_t N>

bool ev::AbstractRepresentation_< T, Options, E >::insert

(

const Array_< E, N > &

array

)

Insert an array of events in the representation.

Parameters

array

Event array to insert

Returns

True if all the events have been inserted

insert() [2/4]

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

bool ev::AbstractRepresentation_< T, Options, E >::insert

(

const Event_< E > &

e

)

Insert one event in the representation.

Parameters

e	Event to insert

Returns

True if the event has been inserted

Note

The way in which the event is inserted should be implemented in the derived classes.

insert() [3/4]

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

bool ev::AbstractRepresentation_< T, Options, E >::insert

(

const Vector_< E > &

vector

)

Insert a vector of events in the representation.

Parameters

vector

Event vector to insert

Returns

True if all the events have been inserted

insert() [4/4]

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

bool ev::AbstractRepresentation_< T, Options, E >::insert	(	Queue_< E > &	queue,
		const bool	keep_events_in_queue = false )

Insert a queue of events in the representation.

Parameters

queue	Event queue to insert
keep_events_in_queue	If true, events are reinserted in the queue

Returns

True if all the events have been inserted

midTime()

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

double ev::AbstractRepresentation_< T, Options, E >::midTime ( ) const

inlinenodiscard

Calculate the midpoint time between the oldest and the newest event.

Returns

Midpoint time. Returns -1 if time limits are not properly set.

setColormap()

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

void ev::AbstractRepresentation_< T, Options, E >::setColormap ( const cv::ColormapTypes cm )

inline

Set colormap for the representation.

Parameters

cm	Colormap type

Note

Colormap can only be used with 3-channel representations.

setTimeOffset()

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

void ev::AbstractRepresentation_< T, Options, E >::setTimeOffset ( const Event_< E > & e )

inline

Set time offset.

Parameters

e

Event

Warning

Offset is set to match the event timestamp, i.e., \(\tau + t = 0\) (where \( \tau \) is the offset and \( t \) is the timestamp of the event).

setValue() [1/2]

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

void ev::AbstractRepresentation_< T, Options, E >::setValue ( const bool polarity, const Type & value )

inline

Set values for ON and OFF pixels.

Parameters

polarity	Positive (ON) or negative (OFF)
value	Value for ON/OFF pixels

setValue() [2/2]

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

void ev::AbstractRepresentation_< T, Options, E >::setValue ( const Type & value )

inline

Set value for non-activated pixels (background).

Parameters

value

Value for non-activated pixels

setValues()

template<typename T , const RepresentationOptions Options = RepresentationOptions::NONE, typename E = int>

void ev::AbstractRepresentation_< T, Options, E >::setValues ( const Type & positive, const Type & negative, const Type & reset )

inline

Set values for ON, OFF, and non-activated pixels.

Parameters

positive	Value for ON pixels
negative	Value for OFF pixels
reset	Value for non-activated pixels
