ee.Image.medialAxis
Computes the discrete medial axis of the zero valued pixels of the first band of the input. Outputs 4 bands:
medial - the medial axis points, scaled by the distance.
coverage - the number of points supporting each medial axis point.
xlabel - the horizontal distance to the power point for each pixel.
ylabel - the vertical distance to the power point for each pixel.

this: image | Image | The input image. |
neighborhood | Integer, default: 256 | Neighborhood size in pixels. |
units | String, default: "pixels" | The units of the neighborhood, currently only 'pixels' are supported. |
