how is it possible to use bwconncomp or in general process a stack of 2000 images with the size of 2000x2000, I dont think block processing would work in this case..

bwconncomp will accept a 3D stack directly. You can specify 2D connectivity with the conn argument.

I meant, how sparse is BW as a volume? In other words, what is
density = nnz(BW)/2000^3
I assume you don't have enough memory to hold BW as a volume, but the density is something you could easily calculate by looping over the slices. If BW is not sparse (low density), you might not even have enough memory to hold the result of the connectivity map.
