摘要
本文深入讨论了三角形网格基(包括DTM和RTM)的活动图像编码方法,包括帧间运动预测及残差图像处理方法等。其中主要涉及三角形网格的分割方法、运动矢量计算和优化方法。实验结果表明,三角形网格基运动补偿比传统的矩形匹配BMA方法有更好的主客观质量。
In this paper the Delaunay triangular mesh (DTM) and regular triangular mesh(RTM) model-based video coding schemes are discussed including inter-frame motion prediction and residual image processing, with the experimental results been illustrated. This paper presents the segmentation method with triangular mesh, the computation of motion vector and its optimization, etc.The results show that DTM and RTM have a better subjective and objective quality than conventional BMA scheme.
