摘　　要：去隔行是电视图像增强处理和视频格式转换的一项关键技术。传统的去隔行算法存在着难以克服的缺陷。文章提出了一种基于运动补偿的自适应去隔行算法,其中包括双向块匹配运动估计,消除块效应和自适应插值三个处理模块。实验证明本算法能够高质量且鲁棒地将场图像重建为帧。De-interlacing is a key tech ni que used in enhancement of TV images and conversion of video scan formats.The c onventional de-interlacing algorithms have some insurmountable faults.A novel de-interlacing algorithm based on motion compensation is presented in this pape r.It is composed of three processing blocks,which are motion estimation based on bi-directional block matching,block effect elimination and adaptive interpo lation.It is proved by experiments that a frame image can be reconstructed perf ectly and robustly from a field image with this algorithm.
