Abstract: This paper studies the MPEG-4 shape encoding technology and video image frame encoding ways,refers to the basic ways of global motion compensation technology,puts forward a forward error concealment method to recover the incorrect image in transmission process,which is based on global motion compensation.Experiment results compared with Cheng ways demonstrate that this method is effective and excellent,especially when the shape information’s lost area is large or the lost part is complicated.

Key words: video image, error concealment, MPEG-4, shape information, global motion compensation

摘要: 深入研究MPEG-4的形状编码技术和视频图像帧的编码方式,参照全局运动补偿技术,在图像形状信息全部丢失、部分丢失信息变化复杂的情况下,提出一种基于全局运动补偿的前向错误隐藏方法对出现传输错误的图像进行恢复。通过与Cheng方法对比仿真实验证明该方法取得很好的恢复效果,尤其是对象形状信息全部丢失时。
