Re-exports

Modules

codec

Expose public API for encoding and decoding

Structs

Coord

Pixel channel address in the ADΔER model

CoordSingle

A 2D coordinate representation

Event

An ADΔER event representation

EventCoordless

An ADΔER event representation

EventCoordlessRelative

EventRelative

EventSingle

An ADΔER event representation, without the channel component

PlaneSize

The size of the image plane in pixels

Enums

Mode

PixelMultiMode

PlaneError

Error type for the PlaneSize struct

SourceCamera

SourceType

The type of data source representation

TimeMode

The type of time used in the ADΔER representation

Constants

D_EMPTY

Special symbol signifying no information (filler dt)

D_MAX

The maximum possible D value

D_NO_EVENT

Special symbol signifying no Event exists

D_SHIFT

Array for computing the intensity to integrate for a given D value

D_SHIFT_F32

Array for computing the intensity to integrate for a given D value

D_SHIFT_F64

Array for computing the intensity to integrate for a given D value

D_START

The default D value for every pixel at the beginning of transcode

D_ZERO_INTEGRATION

Special symbol signifying no information (filler dt)

EOF_PX_ADDRESS

Special pixel address when signifying the end of a sequence of Events

MAX_INTENSITY

The maximum intensity representation for input data. Currently 255 for 8-bit framed input.

Functions

is_framed

Is the given source camera a framed source?

open_file_decoder

Helper function for opening a file as a raw or compressed input ADΔER stream

Type Aliases

AbsoluteT

Absolute firing time (in ticks) of an event. For a given pixel, this will always be grater than or equal to that of the pixel’s last fired event.

BigT

Large count of ticks (e.g., for tracking the running timestamp of a sequence of Events

D

Decimation value; a pixel’s sensitivity.

DeltaT

Number of ticks elapsed since a given pixel last fired an Event

Intensity

Measure of an amount of light intensity

PixelAddress

Pixel x- or y- coordinate address in the ADΔER model

UDshift

Precision for maximum intensity representable with allowed D values
