In this paper, the relationship between the traditional motion estimation method and the general rate distortion framework is analysed. Based on the theoretical analysis, a new rate distortion optimised motion estimation method is proposed under a general rate distortion framework. The proposed method improves the rate distortion performance of video codecs, while the increase in computational complexity remains negligible. Extensive experimental results confirm the effectiveness of the proposed motion estimation method.
