# Quality Assessment of HDR/WCG Images Using HDR Uniform Color Spaces
## Appendix B Performance Indexes  
In this appendix, we present the numerical value for the performance indexes presented in Section 3.2 of each quality metrics with each database. The metrics with the best performances in terms of SROCC and PCC is in red, the second is in blue and the third in green. \begin{table}
