Hi,
Finding unique labels is not necessary when order == 0. In DownsampleSegForDSTransform2 in nnunet, this function is called multiple times, and it all adds up, especially in the limited CPU scenario with high-res images. By introducing this change, I've reduced the time of this transform from ~2 seconds to ~0.2 seconds.
Best,
