HRegion HImage.PlateausCenter()

Description

plateaus_centerplateaus_centerPlateausCenterPlateausCenterPlateausCenter 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.

Parameters

ImageImageImageImageimage (input_object) singlechannelimage(-array) → object (byte / direction / cyclic / int1 / int2 / uint2 / int4 / int8 / real)

Input image.

PlateausPlateausPlateausPlateausplateaus (output_object) region-array → object
