An edge-preserving high-resolution image reconstruction
Monia Discepoli, Ivan Gerace, R. Pandolfi · 2004
In many visual problems, line variables, associated to the discontinuities present in the ideal image, are used to obtain better results. In this paper we propose to extend the use of line variables to the high-resolution reconstruction problem. Moreover, we impose that parallel discontinuities should not be close. To minimize the energy function related to this problem we use a CATILED (convex approximation technique for interacting line elements deblurring) algorithm. Experimental results confirm the goodness of this technique.
