Segmentation Difference is algorithm for comparison of two segmentations to determine how close they are.

Windows

For Windows, use Visual Studio with SD3.sln and build the solution. You can build 'Reindex' project to reindex second segmentation to match segment numbers in best effort approach.

Python tool

In a Unix shell:

pixi install
pixi shell
source compile.cmd

And then in a Python3 interpreter:

from SD3 import sd3
metric_value = sd3(numpy_2d_array, numpy_2d_array)
