Types

DetectorViewBase

android

abstract class DetectorViewBase<T>(context: Context, attrs: AttributeSet) : View

Base class for View implementations which visualize detected results on top of the image preview. Derived classes should implement drawDetection method to perform actual drawing.

PreviewImageBounds

android

data class PreviewImageBounds(x: Float, y: Float, width: Float, height: Float)

Defines location and size of the actual preview image relative to the PreviewView. This information can be used to convert from the image coordinate system to the view coordinate system.

Functions

bounds

android

fun Canvas.bounds(): PreviewImageBounds

Create PreviewImageBounds originating in the top-left corner of this Canvas object and matching its dimensions.

drawLandmark

android

fun Canvas.drawLandmark(landmark: Landmark, paint: Paint, radius: Float, bounds: PreviewImageBounds = bounds())

Draw a given landmark on the Canvas using paint and radius.

drawLandmarks

android

fun Canvas.drawLandmarks(landmarks: List<Landmark>, paint: Paint, radius: Float, bounds: PreviewImageBounds = bounds())

Draw given landmarks on the Canvas using paint and radius.

drawMultiplePoses

android

fun Canvas.drawMultiplePoses(detectedPoses: MultiPoseDetectionResult, landmarkPaint: Paint, edgePaint: Paint, objectPaint: Paint, labelPaint: TextPaint, landmarkRadius: Float, bounds: PreviewImageBounds = bounds())

Draw given detectedPoses on the Canvas using landmarkPaint and landmarkRadius for the pose vertices, edgePaint for the poses edges, objectPaint for the bounding box and labelPaint for the label.

drawObject

android

fun Canvas.drawObject(detectedObject: DetectedObject, paint: Paint, labelPaint: TextPaint, bounds: PreviewImageBounds = bounds())

Draw given detectedObject on the Canvas using paint for the bounding box and labelPaint for the label.

drawObjects

android

fun Canvas.drawObjects(detectedObjects: List<DetectedObject>, paint: Paint, labelPaint: TextPaint, bounds: PreviewImageBounds = bounds())

Draw given detectedObjects on the Canvas using paint for the bounding box and labelPaint for the label.

drawPose

android

fun Canvas.drawPose(detectedPose: DetectedPose, landmarkPaint: Paint, edgePaint: Paint, landmarkRadius: Float, bounds: PreviewImageBounds = bounds())

Draw given detectedPose on the Canvas using landmarkPaint and landmarkRadius for the pose vertices, and edgePaint for the pose edges.

getPreviewImageBounds

android

fun getPreviewImageBounds(sourceImageWidth: Int, sourceImageHeight: Int, viewWidth: Int, viewHeight: Int, scaleType: PreviewView.ScaleType): PreviewImageBounds

Calculate the location of the preview image top-left corner (relative to the component top-left corner) and dimensions, to be used for displaying detected objects, for example with the DetectorViewBase.
