Graph modelling of 3D geometric information for color consistency of multiview images

In this paper we address the problem of multiview color consistency. We propose to use a graph model of 3d positions obtained using matched dense feature points. We define an energy functional on this model which captures relationship of the colors across views while also imposing a smoothness cost to obtain optimal colors for the 3d positions. We finally recolorize the images using these optimal colors at re-projected co-ordinates. An important feature of the proposed method is that it does not use a reference view. Finally we present a qualitative evaluation of our method with methods that use a reference view.
