Abstract— In this paper, a novel frame rate up conversion (FRUC) using modified adaptive bilateral motion estimation (MAEBME) is proposed. Traditionally, extended bilateral motion estimation (EBME) carries out bilateral motion estimation (BME) twice on the same region, therefore has high complexity. Adaptive extended bilateral motion estimation (AEBME) is proposed to reduce complexity and increase visual quality by using block type matching process and considering frame motion activity. In MAEBME algorithm, calculated edge information is used to detect a global scene cut change, and then is used in block type matching process whether to use EBME. Finally, overlapped block motion compensation (OBMC) and motion compensated frame interpolation (MCFI) are adopted to interpolate the intermediate frame. OBMC is adopted adaptively by considering frame motion activity. Experimental results show that this proposed algorithm has outstanding performance and fast computation comparing with the anchor algorithms.
