Frame rate conversion requires interpolation of image frames at time instances to increase the frame rate. In this paper we propose a new fast algorithm for block motion vector(MV) estimation based on the temporal and spatial correlations. Firstly, every nine neighboring blocks are treated as a macro-block; full search block matching algorithm is used to estimate the motion vector of the center block...
In this paper, based on the Xilinx XUP V5-LX110T board, a video post processing platform with a professional HDMI interface circuitry is designed and a novel de-interlacing algorithm is designed, which performs better than the industry leading algorithms as experimental results show. This platform is to verify our HD video post processing SOC chip which is under development.
In this work, we propose a new frame rate conversion algorithm (FRCA) based on adaptive motion estimation and compensation. In the proposed algorithm, an adaptive diamond strategy is firstly used to find out all the motion vectors for each block by adaptively applying diamond algorithm in the current frame. Secondly, the motion vector for each block is further refined by full search algorithm to reduce...
In this paper, we propose a low-complexity motion estimation algorithm for frame rate conversion. Insteading of using sum of absolute difference (SAD) calculation, the algorithm adaptively uses simple comparison operation in different hierarchical motion estimation level to achieve good image quality and fast processing capability. Experiments are carried out on applying this algorithm for frame rate...
