Paper Abstract

In this paper, an adaptive stereo matching method using a sequence of the balanced stereo image pair is proposed. The balanced stereo image pair can be acquired by applying the balance compensation scheme to the input stereo image pair, and then stereo matching is carried out by using the disparity vectors estimated from this balanced stereo image pair, in which the matching window size for disparity estimation is adaptively selected depending on the magnitude of the feature values. Because the balance compensation is able to alleviate the problem of luminance imbalance between the input stereo image pair, performance of the disparity estimation can be improved. Moreover, since the resultant image-smoothing effect occurring in the balanced stereo image can help to reduce not only the unreliable intensity matching but also the ambiguous matching in the process of disparity estimation, effective reconstruction of the stereo image can be expected as well. From some experiments using stereo image pairs of 'Piano' and 'Claude', it is shown that the proposed method improves the PSNR of a reconstructed image up to 6.08 dB on average within the search ranges of ∮± 30 by comparing with that of conventional algorithms.
