A comparison of three shape reconstruction methods on the experimental data.
(a)The shapes reconstructed using VM_SCS under the condition of a given soma position, denoted by black points. (b) The shapes reconstructed using rayburst sampling that a rays were casted from a soma position (black points) and the threshold method were used to compute the length of the ray. (c) The shapes reconstructed using active contour model. All the initial boundaries were circles centered on their soma positions (black points) and whose radiuses were set to 5 µm for best results. (a) – (c) The results for two subareas (small black squares) selected for comparison and further enlarged (big black squares). Note that, in the enlargement, the reconstructed shapes of different somas were distinguished using different colors and the points or open curves that the arrows pointed towards still denote the reconstructed results.
