It returns an image with four bands: `medial` (medial axis points scaled by distance), `coverage` (number of supporting points), `xlabel` (horizontal distance to the power point), and `ylabel` (vertical distance to the power point). The function accepts an input image, neighborhood size (default: 256 pixels), and units (only 'pixels' supported). It is called using `Image.medialAxis()`.\n"]]
