Generates a plus-shaped boolean kernel.
| Usage | Returns |
|---|---|
ee.Kernel.plus(radius, units, normalize, magnitude) | Kernel |
| Argument | Type | Details |
|---|---|---|
radius | Float | The radius of the kernel to generate. |
units | String, default: "pixels" | The system of measurement for the kernel ('pixels' or 'meters'). If the kernel is specified in meters, it will resize when the zoom-level is changed. |
normalize | Boolean, default: true | Normalize the kernel values to sum to 1. |
magnitude | Float, default: 1 | Scale each value by this amount. |
Examples

print('A plus kernel', ee.Kernel.plus({radius: 3}));
