Name

plateaus_centerplateaus_centerplateaus_centerPlateausCenterPlateausCenter — Detect the centers of all gray value plateaus.

Signature

plateaus_center(Image : Plateaus : : )

Herror plateaus_center(const Hobject Image, Hobject* Plateaus)

Herror T_plateaus_center(const Hobject Image, Hobject* Plateaus)

Herror plateaus_center(Hobject Image, Hobject* Plateaus)

HRegionArray HImageArray::PlateausCenter() const

void HOperatorSetX.PlateausCenter(
[in] IHUntypedObjectX* Image, [out] IHUntypedObjectX** Plateaus)

IHRegionX* HImageX.PlateausCenter()

static void HOperatorSet.PlateausCenter(HObject image, out HObject plateaus)

HRegion HImage.PlateausCenter()

Description

plateaus_centerplateaus_centerplateaus_centerPlateausCenterPlateausCenter extracts all points from ImageImageImageImageimage with a gray value greater or equal to the gray value of its neighbors (8-neighborhood) and returns them in PlateausPlateausPlateausPlateausplateaus. If more than one of these points are connected (plateau), their center of gravity is returned. Each plateau center is returned as a separate region.
