In order for algorithms to be successful in a diverse range of applications it is important that they achieve suitable levels of robustness. We believe it is possible to improve algorithmic robustness by integration of results in a temporal feedback loop. In particular by fusing data from a sequence of stereo image pairs, and `bootstrapping' the matching process in each frame with the disparities from the previous frame. We shall demonstrate how, for our existing stereo algorithm, the reliability in terms of mismatch rates can be greatly improved by introducing such a feedback path. Temporal processing offers the additional benefit of reducing computational load, typically accelerating the execution of our algorithm four-fold.
