Optical EngineeringDeinterlacing with reduced flickering
|Format||Member Price||Non-Member Price|
Deinterlacing has been used to convert interlaced video signals into progressive video signals. Conventional deinterlacing methods with low levels of complexity can lead to deteriorating video quality, particularly in edge areas. Another problematic artifact is flickering, which occurs more frequently as the video size increases. For example, this flickering artifact is more frequently observed in high-definition television signals. In this paper, we propose a flickering artifact reduction algorithm for deinterlacing, which noticeably increases the overall visual quality.
