(a)–(c) Results reconstructed using EPTV combining with 2-, 4-, and 8-directional gradient operators, respectively. Areas marked by dotted ellipses are the differences of the results between 4-, and 8-directional gradient operators. Even if combined with EPTV, the images reconstructed from more number of directions in gradient operators still have less artifacts.</p
