Abstract

The paper addresses a problem of perceptual artifacts that appear in Y'CbCr non-linear luminance 4:2:0 HDR video. A computationally inexpensive method is proposed for converting the 4:4:4 HDR video to Y'CbCr 4:2:0 nonconstant luminance format. The method removes artifacts in areas with saturated colors. The approach obtains results in one step, improving the average linear light PSNR by 2.16 dB and tPSNR metric by 1.99 dB on the investigated videos.
