The VCEG test conditions detailed in [1] recommend using the Bjontegaard metric described in [2] to provide relative gain between two methods, by measuring average difference between the two RD-curves.
We propose to make available to VCEG an Excel add-in that computes this metric. As an additional feature, this add-in allows to provide the bitrate saving between two methods, for a given objective quality and the PSNR-Y delta for a given bitrate which allows drawing the evolution of the metric.
