| Abstract: | Due to the versatility of real-world video formats,format conversion has become indispensable in modern video display systems. A new motion adaptive de-interlacing algorithm is proposed which integrates edge-preserving median filtering algorithm and average filtering algorithm together by weight. It has advantages of easy implementation and high hardware utilization. This algorithm has been verified by C model and Xilinx FPGA and is applied in real-time video processing SOC. Morever,the hardware implementation block diagram and system performance are provided as well. |
