ee.Kernel.rectangle
Generates a rectangular-shaped kernel.
Usage | Returns | ee.Kernel.rectangle(xRadius, yRadius, units, normalize, magnitude) | Kernel |
Argument | Type | Details | xRadius | Float | The horizontal radius of the kernel to generate. |
yRadius | Float | The vertical 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
