this:
image
|
Image | The input image. |
metric
|
String, default: "sam" | The spectral distance metric to use. One of 'sam' (spectral angle mapper), 'sid' (spectral information divergence), 'sed' (squared Euclidean distance), or 'emd' (earth movers distance). |
kernel
|
Kernel, default: null | Connectedness kernel. Defaults to a square of radius 1 (8-way connected). |
useCentroid
|
Boolean, default: false | If true, distances are computed from the mean of all pixels under the kernel instead of the kernel's center pixel. |
