In this work a novel scheme is proposed for adaptive early SKIP mode decision in the multiview video coding based on mode correlation in the 3D-neighborhood, variance, and ratedistortion properties. Our scheme employs an adaptive thresholding mechanism in order to react to the changing values of Quantization Parameter (QP). Experimental results demonstrate that our scheme provides a consistent time saving over a wide range of QP values. Compared to the exhaustive mode decision, our scheme provides a significant reduction in the encoding complexity (up to 77%) at the cost of a small PSNR loss (0.172 dB in average). Compared to state-of-the-art, our scheme provides an average 2x higher complexity reduction with a relatively higher PSNR value (avg. 0.2 dB).
