Computes the Bjontegaard metric for two set of RD points. The Bjontegaard metric enables the comparison of RD curves in terms of the average PSNR improvement or the average per cent bitrate saving. Although the original Bjontegaard metric works with 4 RD points, this script is able to handle RD curves with an arbitrary set of points. Look the embedded test_bjontegaard file for an example of usage.
