- Abstract
- As the video industry supports UHD resolution, the discussion of the HDR/WCG technology for realvideo are underway. Many techniques for light intensity and color gamut discussed by experts offer viewers an experience of realness. To encode HDR sequences, HEVC Main10 profile is used after HDR-to- SDR format conversion (i.e. HDR10 process). Through HDR10 process, the conversion from a half float 4:4:4 RGB linear-light format with high bit to 4:2:0 10bits Y’CbCr is obtained. HDR output sequence can be obtained by performing a reverse process, HEVC decoding and SDR-to-HDR format conversion. The loss of image information occurs in the above procedure, especially in Y’CbCr down/up-sampling procedure. In this work, we experimented with different filters to optimize HDR10 down/up-sampling process. We implemented the core techniques of HDR10 in Matlab programming in order to utilize the existing filters. In this paper, the necessity of the filter selection algorithm in down-conversion process is proposed. By presenting the difference between the CIE1931 x’y’ gamut of several filters, we show a variety of problems that can occur in the HDR video compression
