Abstract : In this work, we consider the problem of propagation-based matching for 3D reconstruction, which deals with expanding a limited set of correspondences towards a quasi-dense map across two views. In general, propagation based methods capture well the scene structure. However, the recovered geometry often presents an overall choppy na-ture which can be attributed to matching errors and abrupt variations in the estimated local affine transformations. We propose to control the reconstructed geometry by means of a local patch fitting which corrects both the matching locations and affine transformations throughout the propagation process. In this way, matchings that propagate from geo-metrically consolidated locations bring coherence to both positions and affine transformations. Results of our approach are not only more visu-ally appealing but also more accurate and complete as substantiated by results on standard benchmarks.
