MultiColourThreshold

open class MultiColourThreshold : Processor<T>

A processor that applies multiple ColourThreshold processors to the same frame and combines their draw results. The MASK variable can be used to select which processor's mask is drawn to the frame.

Since

1.0.0-pre

Constructors

MultiColourThreshold

constructor(@NonNull thresholdProcessors: Array<ColourThreshold>)

Create a new MultiColourThreshold with the given processors.

Properties

MASK

open var MASK: Int

The index of the processor mask to draw to the frame.

Inherited properties

cameraDimensions

@get:Nullable

open val cameraDimensions: Size

data

protected val data: List<T>

List of all vision data detected since the last stateful update.

isFlipped

open var isFlipped: Boolean

isRunning

open val isRunning: Boolean

Functions

getId

@NonNull

open fun getId(): String

Unique identifier for the processor.

init

open fun init(@Nullable calibration: CameraCalibration)

Optional method to implement to access the camera calibration data.

onAttach

protected open fun onAttach()

Override this method to run any additional code that will be executed when this processor is attached (via init()) by a Vision instance.

onFrameDraw

protected open fun onFrameDraw(@NonNull canvas: Canvas)

Called by the vision system to draw on the frame.

onProcessFrame

protected open fun onProcessFrame(@NonNull frame: Mat, captureTimeNanos: Long)

Called by the vision system to process a frame.

update

protected open fun update()

Called to update new data from the vision system, which involves interpreting, collecting, or otherwise processing new vision data per frame.

Inherited functions

clearData

open fun clearData()

Manually clear the data list.

delegate

open fun delegate(@NonNull delegateTo: Processor)

Delegate this processor to another processor.

getData

@NonNull

open fun getData(): ArrayList<T>

Get the list of vision data.

getFrameBitmap

open fun getFrameBitmap(@NonNull continuation: Continuation<out Consumer<Bitmap>>)

abstract fun getFrameBitmap(p: Continuation<out Consumer<Bitmap>>)

init

fun init(width: Int, height: Int, @Nullable calibration: CameraCalibration)

abstract fun init(p: Int, p1: Int, p2: CameraCalibration)

isAttached

open fun isAttached(): Boolean

Determine whether the processor is attached to a Vision instance or is initialised.

onDrawFrame

fun onDrawFrame(@NonNull canvas: Canvas, onscreenWidth: Int, onscreenHeight: Int, scaleBmpPxToCanvasPx: Float, scaleCanvasDensity: Float, @NonNull userContext: Any)

Use onFrameDraw instead, which passes a canvas.
