Table 1. Table comparing original and recovered ${\tau }_c$ values and residual norm $(l_2)$, where the first two rows shows the recovered ${\tau }_c$ without and with prior and the third row shows the recovered ${\tau }_c$, with speckle contrast data in optimal exposure range. The fourth row shows recovered ${\tau }_c$ and residual norm for the iterative scheme.
