How a candidate segmentation b corrupts the wiring diagram of truth a, in bits.
Two levels, both VOI split / merge (synapses as in seg_synapse_partners):
• synapse ends (split / merge, voi): the segmentation VOI measured only at the 2n synapse ends instead of every pixel. split = two ends on one true neuron now on different objects (the neuron was cut between its synapses); merge = ends on different true neurons now on one object (they were glued). Cutting a neuron whose s ends divide s1 / s2 raises split by exactly (s / 2n)·H2(s1 / s). Pixels far from any synapse cost nothing here.
• connections (connection_split / connection_merge): synapses grouped by their (pre object, post object) pair — one true connection scattered over several, or different true connections fused into one (synapses attributed to the wrong partner). A connection with a single synapse cannot scatter, so this level is blind to cuts that only rename a one-synapse connection; the ends level is not.
Provenance: the ends level is the "synapse VI" of Plaza, Scheffer & Chklovskii 2014 (*Focused proofreading*, arXiv:1409.1199; VI over the voxels carrying synaptic annotations, implemented in NeuroProof, C++). The connection level, the lost-synapse convention and the per-edit closed forms ((s/2n)·H2(s1/s) for a cut) are this module's. Synapses with an end on background in the truth are dropped; in the candidate, each such synapse is lost and counted in n_lost as its own singleton at both levels (not one shared "background" object, which would fake a huge merge). Also returns split_connections (true connections spread over 2+ candidate ones), merged_connections (candidate connections holding synapses of 2+ true ones), edges_a / edges_b and n (synapses scored).
Raises ValueError: as seg_synapse_partners; shapes of a and b differ; no synapse left after dropping background in the truth.
