working memory is bounded by the slab — not the volume.
The third leg of the memory family: :func:vol_crop_domain shrinks where
you compute, :mod:volregion shrinks what you keep, and this bounds how
much lives in RAM at once. Each slab vol[z0-overlap : z1+overlap] is
run through fn and only the core [z0:z1) of the result is kept, so a
volume far above an operator’s comfortable size streams through in
constant-memory pieces (measured: peak working set of a Gaussian drops with
the slab size while the output stays exact — see the test).
Correctness contract (the honest part): the result equals fn(vol)
exactly only for local operators whose spatial footprint along z is at
most overlap voxels on each side (a Gaussian of sigma s with scipy’s
default truncation needs overlap >= round(4 * s); a morphology with a
k-voxel structuring element needs overlap >= k). A global operator
(Otsu, normalisation, anything that looks at the whole histogram) is
silently WRONG under tiling — this function cannot detect that, so it is
documented instead: do not tile global operators.
Parameters: fn is any callable mapping a (d, H, W) float64 volume to
an array of the same shape (e.g. lambda v: vol_gradient_magnitude(v)).
tile is the slab thickness (>= 1), overlap the per-side context
(>= 0). A slab result of the wrong shape raises ValueError immediately
(fail-closed — a shape-changing fn would silently corrupt the assembly).
