Hi,

In OTB, segmentation algorithms use multi-channel images to perform the segmentation. The similarity between pixels is computed based on a spectral distance (taking into account all the stacks, as spectral bands). It doesn't compute a mean layer.

Hope it helps,

Guillaume

Hi,

I want to ask how the segmentation algorithms (meanshift, large scale meanshift and watershed) segment raster stacks.

Do they calculate the mean from all layers and then segment this mean-layer?

Best, Wruke
