Improved high dynamic range video coding with a nonlinearity based on natural image statistics. International Journal of Signal Processing Systems. 2017;5(3):100-5. DOI: 10.18178/ijsps.5.3.100-1051939-8018http://hdl.handle.net/10230/42151High Dynamic Range (HDR) technologies support the capture and presentation of a wider range of luminance values than conventional systems. An important element of video processing is the transfer function which should emulate human perception and this needs to be revisited for HDR content and displays. In the paper, we adapt a nonlinearity designed for the tone-mapping problem to the problem of video coding. We test the nonlinearity using the Motion Picture Experts Group methodology and find it can outperform existing methods in terms of HDR video quality measure.application/pdfeng© 2017 International Journal of Signal Processing SystemsImproved high dynamic range video coding with a nonlinearity based on natural image statisticsinfo:eu-repo/semantics/articlehttp://dx.doi.org/10.18178/ijsps.5.3.100-105High Dynamic Range (HDR)HDR-television (HDR-TV)Transfer Function (TF)Video codingVideo compressioninfo:eu-repo/semantics/openAccess
