Regional mutual information-based identification and reduction of flicker artifacts during video encoding

  • Vinay Kumar
Original Paper


Present manuscript discusses a novel technique to identify flicker-prone regions in video and reduce its effects. The flicker-prone regions are identified with the help of regional mutual information which takes into account the geometrical properties of the frames while requiring no prior information about the data under consideration, which makes it suitable for video-processing applications. The flicker-prone regions are passed through a temporal filter before standard compliant encoding of the video sequence. Accurate measurement of the flicker-prone regions and independence of the encoding methodology makes the proposed method suitable for wide variety of encoders.
