Abstract

This paper considers the problem of automatic registration of stereo images with little or no occlusion. The chosen strategy is based on multiresolution (MR) representations of both the images and the unknown, locally-varying warping map, and uses a coarse-to-fine refinement strategy in which successively more image detail is processed to obtain successively finer- scale corrections to an initial, global estimate of the warping map. The definition of an 'optimal' MR registration algorithm under this strategy is set out in terms of maximizing the chances of fast convergence to the true disparity. We set out the equations for a specific version of this strategy in which spline models of different orders are used for both MR representations. The resulting algorithm, which requires hardly any prior parameter adjustment, shows both robustness and flexibility in tests on both synthesized and real image pairs. Indeed, its performance suggests that it comes close to meeting the previously defined optimality criterion.
