| 摘 要： | 算法基于H.264的灵活宏块次序(FMO),在编码端,每个宏块提取中部的4个像素值,嵌入到下个帧的对应遮蔽片中;在解码端,提取出重要数据,根据场景是否切换在空域和时域的方法之间选择,在空域方法中又根据纹理复杂程度对两种插值算法进行自适应以达到提高I帧主客观质量的目的.实验证明了新算法的有效性.

| Abstract: | The proposed scheme is based on Flexible Macro-block Ordering(FMO) of H.264. At encoding end, four pixels of each micro-block are extracted and embedded into corresponding hiding slice in next frame. In decoding end, the methods in temporal and spatial are selected according to whether the scene switches. Finally, the above two schemes are adapted in spatial domain based on complicate degree of veins, in order to improve the objective and subjective quality of I frame. The experimental results prove the eff... |
