According to investigating impact of complexity of
\r\nstereoscopic frame pairs on stereoscopic video coding and
\r\ntransmission, a new rate control algorithm is presented. The proposed
\r\nrate control algorithm is performed on three levels: stereoscopic group
\r\nof pictures (SGOP) level, stereoscopic frame (SFrame) level and
\r\nframe level. A temporal-spatial frame complexity model is firstly
\r\nestablished, in the bits allocation stage, the frame complexity, position
\r\nsignificance and reference property between the left and right frames
\r\nare taken into account. Meanwhile, the target buffer is set according to
\r\nthe frame complexity. Experimental results show that the proposed
\r\nmethod can efficiently control the bitrates, and it outperforms the fixed
\r\nquantization parameter method from the rate distortion perspective,
\r\nand average PSNR gain between rate-distortion curves (BDPSNR) is
\r\n0.21dB.<\/p>\r\n","references":"
