Quantitative comparison of the performance of the algorithms to noise. We plot the reconstruction error, evaluated using different metrics, as a function of the SNR of the measurements. Note that the level-set algorithm fares significantly better than the other under the SE and SCE criteria, in clear agreement with the visual comparisons. The MSE criterion indicates worse results. As discussed below, this is mainly due to the limitation of the MSE in comparing two piecewise constant functions.
