摘要：Sub-pixel accuracy image registration is needed for many applications. In order to achieve this accuracy, one uses image re-sampling. Since the image interpolation step is performed a high number of times, approximate interpolations are performed in order to reduce computation cost. In this paper we study the artifacts introduced in the disparity map estimation by the approximate interpolation and propose stategies in order to reduce them
