A PDES METHOD PRESERVING BOUNDARIES ON DENSE DISPARITY MAP RECONSTRUCTION
Ji Liu, Junjian Peng, Yuechao Wang, Yandong Tang · 2008
Over smoothness restricts the application of PDEs in the field of dense disparity map reconstruction, because disparity map reconstruction usually requires preserving discontinuousness in some areas such as the boundaries of objects. To preserve disparity discontinuousness, this paper adopts two strategies. Firstly, ground control points (GCPs) are introduced as the soft constraint. Secondly, this paper designs a structure of smoothness part in energy functional, which can preserve discontinuousness effectively. Moreover, the adjustable parameters in the smoothness part advance its robustness. In experiments, we compare proposed method with graph cuts method and prove that PDEs is also a useful solution for disparity map reconstruction and has the advantage of dealing with smooth images.
