One of the key problems in Augmented Reality systems is registration, that is to say the synchronization of real and virtual world. Augmented reality uses a lot of different sensors in order to estimate camera or operator's point of view. These sensors could provide samples faster than mixing of virtual and real informations could be displayed. We expose here a way to take into account samples that are generated during the mixing process. This method is using a post-rendering technique involving a tex-ture to perform this task. We will expose the errors reduction obtained by performing such technique with a simulation test-bench implementing our proposal.
