In order to minimize the transmission errors for stereoscopic images

we propose an error concealment algorithm based on local reliable disparities.First

taking the block loss and the factors of color similarity and geometric distance proximity into account

we design a base-point-biased window to conduct the adaptive weight disparity matching.Second

local reliable disparities are calculated according to the disparity constancy and left-right consistency.Finally

the Winner-Takes-All (WTA) strategy is adopted to estimate the disparity of lost block which will be used to get the data of corresponding block for error concealment.Experimental results show that compared with other algorithms

the proposed method can produce better PSNR and subjective quality of reconstructed image while the computational complexity is almost the same.
