The VLSI design of motion adaptive de-interlacing with horizontal and vertical motions detection

Video de-interlacing techniques, which convert the format of interlaced images to progressive images, are important today to improve the quality of display. Motion adaptive de-interlacing techniques are capable of improving the quality of the visual results. Most of them focus on the static or horizontal motion detection only, nevertheless, their performances are also affected by vertical motion. The vertical motion tends to destabilize the quality of performance while de-interlacing technique is utilized. This paper presents the VLSI design of the proposed de-interlacing method which takes both horizontal and vertical motions into account. The proposed technique, which consists of intrafield de-intertacing by median edge dependent interpolation, Median EDI, and interfield de-interlacing with horizontal and vertical motions detection, provides a simple hardware architecture design with low computation cost that is easy to implement in real-time hardware.
