ETRO's Bjontegaard Metric implementation for Excel.
Excel VBA code for calculating Bjontegaard Delta SNR and Rate, using arbitrary number of data points. The calculated results comply with VCEG-M33 when using 4 data points.
Provides two functions (all arguments take cell ranges):
BDSNR(BR1, PSNR1, BR2, PSNR2) BDBR(BR1, PSNR1, BR2, PSNR2)
These functions are provided in two versions (both containing the exact same VBA code):
bjontegaard_etro_standalone_example.xlsm is a stand-alone Excel sheet with the VBA routines internally in the file. It’s a macro-enabled Excel worksheet.
bjontegaard_etro.xla is an Excel Add-In. By adding this on your system (via Excel Add-In preferences), the two functions become globally available in your Excel install.
