Announcement: On
November 13, 2024, all users will need to
use a Cloud project in order to access Earth Engine. After this date, continued individual access without a Cloud project will require
an exception.
ee.Image.focalMedian
Applies a morphological reducer() filter to each band of an image using a named or custom kernel.
| Usage | Returns | Image.focalMedian(radius, kernelType, units, iterations, kernel) | Image |
| Argument | Type | Details | this: image | Image | The image to which to apply the operations. |
radius | Float, default: 1.5 | The radius of the kernel to use. |
kernelType | String, default: "circle" | The type of kernel to use. Options include: 'circle', 'square', 'cross', 'plus', 'octagon', and 'diamond'. |
units | String, default: "pixels" | If a kernel is not specified, this determines whether the kernel is in meters or pixels. |
iterations | Integer, default: 1 | The number of times to apply the given kernel. |
kernel | Kernel, default: null | A custom kernel. If used, kernelType and radius are ignored. |
