Intra-frame motion compensation based on linear interpolation padding
基于线性插值填充的帧内运动补偿

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.
