英文摘要 | This paper presents a motion adaptive de-interlacing technique with precise interfield information by global and local scene change detection. Scene changes happen fairly often in film broadcasting and they tend to destabilize the quality of performance, introducing various problems including jagged effect, blurred effect, or artifacts effect, when the de-interlacing technique is utilized. The proposed method utilizes the low computational complexity of the de-interlacing technique to improve video sequences on progressive devices. Our new scene change detection method for de-interlacing uses the interfield information for interpolation. The scene change detection scheme, executed at the first stage of de-interlacing, ensures that the interfield information can be used correctly. Before the interfield information is used for temporal interpolation, the background area is recognized if the state of non-motion lasts for a period of time. The simulation results indicate that increasing the precision and stability of the interfield information promotes the quality of video sequences. The results also show that the proposed method presents a higher quality of video sequences than other interpolation methods. |
