该文提出一种基于人脸对称性的差错掩盖方法。首先进行肤色分割，判断出肤色区域；然后对检测出的肤色区域进行对称性判断，选出对称的人脸区域并采用人脸对称掩盖算法进行差错掩盖，对其它区域则采用自适应插值算法。采用H．264的JM86模型对算法进行验证，实验结果表明，与传统的插值算法相比，该文算法利用了人脸的对称性，对于对称的人脸区域获得了更好的掩盖效果。

This paper presents an error concealment method based on facial symmetry .We first execute color segmentation , determine the skin color region;then judge the symmetry of this region , conceal symmetry face regions with symmetry algorithm , conceal other regions with adaptive interpolation algorithm .Using JM86 model of H.264 standard to simulate the algorithm , the experimental results show that our method achieves better conceal results when compared with traditional interpolation algorithm .
