In this article, we present a novel stereo reconstruction algorithm that propagates disparity information around a set of candidate feature matches. This has the advantage of avoiding problems with specular highlights, occlusions from instruments and view dependent illumination bias. Furthermore, the algorithm can be used with any feature matching strategy allowing the propagation of depth in very disparate views. Validation is provided for a phantom model with known geometry and this data is available online in order to establish a structured validation scheme in the field. The practical value of the proposed method is further demonstrated by reconstructions on various in vivo images of robotic assisted procedures, which are also available to the community.", 17isbn="978-3-642-15705-9" 18} 19 20@article{Lhuillier2000, 21abstract = {A new robust dense matching algorithm is introduced.

Two most$\backslash$ndistinctive features are a match propagation strategy developed by$\backslash$nanalogy to region growing and a successive regularisation by local and$\backslash$nglobal geometric constraints.
