- Abstract:
This paper presents a novel algorithm that improves the localization of disparity
discontinuities of disparity maps obtained by multi-baseline stereo.
Rather than associating a disparity label to every
pixel of a disparity map, it associates a position to every disparity
discontinuity.
This formulation allows us to find an approximate solution to a 2D
labeling problem with robust smoothing term by minimizing multiple 1D
problems, thus making possible the use of dynamic programming.
Dynamic programming allows the efficient computation of the visibility
of most of the cameras during the minimization.
Whilst the proposed minimization strategy is particularly suitable for
stereo with occlusion, it may be used with other labeling problems.
