JCTVC-B055 [K. Senzaki, K. Chono, H. Aoki, J. Tajime, Y. senda (NEC)] BD-PSNR/rate computation tool for five data points

This contribution presented a BD-PSNR/Rate computation tool for five data points. The new BD-PSNR/Rate computation tool is based on C code, and computes BD-PSNR/Rate values in the same manner as the Excel macros embedded in JCTVC-A031. Unlike the Excel macros, the C-code can be compiled on any platform. The compiled binary executable is friendly to batch processing, and its usage is very similar to that of AVSNR4 which many of the JCT-VC experts are familiar with. The BD-PSNR/Rate mismatch between the C-code and the Excel macros is reportedly negligibly small. The appended C code was proposed as the BD-PSNR/Rate computation tool for five data points for the future activities of JCT-VC.

This software seems useful for experiments that will use five data points rather than four, although we are currently using four for most planned experiments. The contributor was thanked for the contribution.

It was remarked that the JCTVC-A031 macros can be used for higher-order evaluations as well as 4 or 5 point scenarios.
