Constructors

ColourBlob

constructor(cameraDimensions: Size?, contour: MatOfPoint, contourPoints: List<Point>, contourArea: Int, density: Double, aspectRatio: Double, boxFit: RotatedRect)

Alternate constructor that supports the usage of the toContourData method, which needs camera dimensions.

constructor(contour: MatOfPoint, contourPoints: List<Point>, contourArea: Int, density: Double, aspectRatio: Double, boxFit: RotatedRect)

Types

Companion

object Companion

Collection of utility functions found via the Util inner class of ColorBlobLocatorProcessor.

Properties

aspectRatio

val aspectRatio: Double

The aspect ratio i.e. the ratio of the longer side of the bounding box to the shorter side.

boxFit

val boxFit: RotatedRect

"Best fit" bounding box for this blob.

contour

val contour: MatOfPoint

The OpenCV contour corresponding to this blob.

contourArea

val contourArea: Int

The enclosed area by this blob's contour.

contourPoints

val contourPoints: List<Point>

The contour points for this blob.

density

val density: Double

The density i.e. ratio of the contour area to convex hull area.

Functions

toContourData

fun toContourData(): ContourData
