摘要:

提出一种针对立体图像传输的差错掩盖方法,该方法根据图像不同的局部特性,结合立体双通道图像间的相关性误码掩盖模式和通道内图像误码掩盖模式的优势,可得到较好的掩盖效果. 实验结果表明,文中所提出的方法与使用通道内误码掩盖方法相比,具有更好的错误隐藏性能,PSNR平均提高1 dB左右.

Abstract:

A new error concealment scheme based on bi-mode for stereoscopic images is proposed, which
makes use of correlation between the two images and error concealments in monoscopic images based on
different local characteristics. Experimental results show that the proposed scheme has good performance
of error concealment for stereoscopic images. The average PSNR is increased by 1 dB as compared to the
monoscopic mode.

Key words: error concealment, correlation, bi-mode, stereoscopic image
