Comparison of three neuron recognition methods applied to a healthy brain with shape criterion and cluster size cut-off (10 pixels) showing that as touching neurons are distinguished the recognition efficiency improves (e.g., the number of recognized neurons increases from 33 to 45 to 54.). Image size is 140 pixels × 140 pixels (122 μm × 122 μm). (a) Simple recognition (optical density cutoff 155). (b) Potts recognition (k_BT = 0.4, θ = 2.5, κ = 10, and optical density cutoff 135). (c) Parallel Potts recognition with 4 × 4 sets of conditions (k_BT = 0.1−1, θ = 0.5−5, κ = 10, and optical density cutoff 135).
