Marcellus shale development metrics.
While evaluated by the regional selective image quality metrics, ΔPMOS_SSIM is 0.78 and ΔPMOS_PSNR is −0.70.
Furthermore, based on the metrics selective criteria, only LDI index and area metrics were incorporated into the assessment schematic.
Moreover, the proposed MVC scheme can save over 20% bit rate with imperceptible image quality degradation according to the evaluation of region selective image quality metrics.
And then, SVA-based bit allocation optimization algorithm is proposed for MVC in Section 4. Section 5 presents the regional selective image quality metrics which are adopted in the coding performance evaluation.
Then, to test for the presence of selective neutrality, several metrics were estimated.
Even though this trend is not significant in vertebrates, the sign of the correlation coefficient is always negative regardless of the metrics of selective constraint (ω or dN) or the data set used (table 2 and fig. 4; supplementary fig. S1 and tables S8 and S9, Supplementary Material online).
Since both SSIM and PSNR have been adopted in advanced video coding standard, H.264/AVC, we apply both the region-selective SSIM and PSNR metrics [34] to evaluate the proposed MVC scheme.
A utility of the FLAGS ranking is that it provides, albeit indirectly, a gene-level indication of the selective constraint upon a gene, while most existing metrics such as phastCons [ 57] or PhyloP [ 58] provide a position-specific value.
Moreover, these four clusters are equally identified when using two different metrics as activity cutoff, further confirming their selective mode-of-action as compared to other clusters.
