TABLE II.

Relative estimation error compared to groundtruth images after sPCA and total variation error of experimental results with varying distribution $\pi =\left({\pi }_1,{\pi }_2\right)$; ${\text{error}}_i$ represents the relative error on image $i=1,2$.

${\text{dist}}_{\text{TV}}$	0.0025	0.0007	0.0022	0.0009	0.0014
${\text{error}}_1$	3.59%	5.01%	1.59%	3.60%	3.95%
${\text{error}}_2$	2.01%	4.66%	0.91%	4.08%	4.63%
