Dаtum izdаvаnjа: | 1-дец-2013 | Čаsоpis: | 2013 11th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Services, TELSIKS 2013 | Sažetak: | H.264 is one of the first video coding standard incorporating coding formats with a bit-depth of above 8 bits. This paper presents the results of compression comparison tests for the H.264 'High 422' profile, between 10-bit and 8-bit sample depths. The simulations were run on five 720p and 1080i high definition sequences. PSNR and SSIM metrics were used to evaluate the objective quality performance of both bit-depths, and with the aim of enabling a fair comparison, both metrics were computed with 10-bit precision, up-scaling the 8-bit decoded sequences to 10-bits. Some works have been published in this field based on the evaluation of commercial 10-bit H.264 implementations. In this work, we carry out a neutral evaluation of H.264 standard performance using the official H.264 Reference Software. Unlike the expected 10-bit coding gains, the results show unnoticeable differences between both sample depths in terms of objective quality, lower 0.1dB for PSNR and 0.002 for SSIM, with a 5% bit rate saving that can be achieved for the luminance component, especially for the 720p format, and negligible quality improvement for U and V chroma components. © 2013 IEEE. | URI: | https://open.uns.ac.rs/handle/123456789/8084 | ISBN: | 9781479909025 | DOI: | 10.1109/TELSKS.2013.6704904 |
