Abstract
In this paper, we propose an improved adaptive interpolation filter method for improving coding efficiency in H.264/ AVC. Although the conventional cost functions have showed a good performance in terms of rate and distortion, it still leaves room for improvement. To improve coding efficiency, we introduce a new cost function which considers the bit rates and distortion for coding the macroblock. The best filter is adaptively selected to minimize the proposed cost function. Experimental results show that the adaptive interpolation filter with the proposed cost function significantly improves the coding efficiency compared to ones using conventional cost function. It leads to about a 5.62% (1 reference frame) and 5.14% (5 reference frames) bit rate reduction on average compared to H.264/AVC, respectively.
