Performance comparison of the proposed method with Tikhonov, Total Variation (TV), and Dual Problem (DP) reconstructions on a real CT dataset of a carved cheese slice with sparse projections.

Performance comparison of the proposed method with Tikhonov, Total Variation (TV), and Dual Problem (DP) reconstructions on a real CT dataset of a carved cheese slice with sparse projections.

<p>The sinogram was acquired from 15 projections over a 360<sup>∘</sup> range.</p>
