Abstract:

In stereo-vision, the goal is to reconstruct the three-dimensional structure of the scene observed from two (or more) camera inputs. The main problem there is the matching of features into both camera frames. In this paper we use a rating scheme of the potential correspondences, based on the multi-modal intrinsic similarity of the features. Then we propose an estimations for feature consistency, and of feature stereo-consistency. This stereo-consistency applied to the neighbourhood of a feature is then used to evaluate the extrinsic similarity between the two features, estimating how the semi-local constellation of features is consistent over stereo. We have applied this process to remove outlier in our stereopsis, over artificial and natural scenes.
