Flicker and black-streak artifact removal from images of display monitors taken by video cameras

In this paper, we focus on removing black streak artifacts from video images of LED and VFD display monitors taken by video cameras. These streak artifacts affect the image recognition of characters displayed on the monitor, and also affect the quality of video compression. To interpolate correct pixel intensities, we apply an image composition method using light blending of images selected at an appropriate frame interval. The frame interval is decided based on the spectrum of the luminance oscillations at each pixel. Our experimental results show some improvements in the appearance of images and in video encoding.
