| 摘 要： | 帧内运动补偿被认为是H.264/AVC中具有潜力的改进方向之一。提出了一种线性插值填充算法来改进帧内运动补偿的编码效率。与Dong等人提出的自适应填充算法相比，线性插值填充能更精确地预测出填充区域内的像素，从而使得帧内运动补偿效率更高。实验测试表明，基于线性插值填充的改进算法可以使帧内运动补偿块数量增加4.58%~84.7%，从而令帧内编码的率失真性能得到提高。

| Abstract: | Intra-frame motion compensation was considered to be one of the potential enhancements of H.264/AVC. A Linear Interpolation Padding (LIP) method was proposed to improve the intra-frame motion compensation. Compared to Adaptive Padding proposed by Dong, LIP can predict the pixels in padding zoom more precisely. And as a result, the efficiency of intra-frame motion compensation will be increased. Experimental results show that LIP can increase the number of macroblocks coded as intra-frame motion compensation by 4.58%~84.7%, and improve the overall rate-distortion performance. |
