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-interlacing 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
