Abstract

In this paper, a local method is proposed to estimate the visibility and disparity of pixels from a stereo pair using the DAISY feature. The problem is formulated as a joint optimization over disparity and visibility of individual pixels. The constraints on the range of disparities and the binary visibility variables are enforced by incorporating penalty terms into the cost function. Finally, the unconstrained optimization problem is solved using a Newton scheme with appropriate approximations to the Hessian matrices and gradients. The computation time of the proposed optimization method is around one minute to run for 768 x 512 stereo pairs using the DAISY feature descriptor in a C++ implementation.
